- An account manager assigned on the platform side; handles escalation, roadmap briefings, beta pilot selection and co-marketing coordination.
09
- Revenue Share / MDF
- Commission, rebate or Market Development Fund received by a partner from the platform; reported transparently to the client each quarter at Roibase.
10
- RFP / POC / Scorecard
- Request for Proposal (question set) -> Proof of Concept (4-6 week test) -> Weighted Scorecard (weighted scoring); the objective trio for vendor selection.
11
- SLA / DPA / Exit Clause
- Service Level Agreement (uptime + support), Data Processing Agreement (KVKK/GDPR), Exit Clause (exit terms + data portability) — the enterprise contract trio.
12
- Certification Matrix
- A team x platform x certification level x validity table; kept visible with expirations, renewal dates and backup expert capacity.
13
- Microservices
- An architecture that splits a single application into small services, each with its own database and deployment cycle. Enables independent scaling + team autonomy; in return introduces distributed-system complexity, observability needs and a service-mesh story.
14
- Monolith
- The traditional architecture where all functions live in a single codebase and ship as one deployment unit. The "modular monolith" variant is faster and cheaper than microservices for small-to-mid teams; "premature decomposition" is the most common trap.
15
- Serverless
- Running code in an auto-scaling function-as-a-service environment without managing infrastructure (AWS Lambda, Cloudflare Workers, Vercel Functions). Pay-per-execution — economical at low traffic, elastic during spikes; the tradeoffs are cold-start latency and vendor lock-in.
16
- CI/CD
- Continuous Integration + Continuous Delivery/Deployment — a pipeline that auto-tests every commit and, when green, ships it all the way to production. GitHub Actions, GitLab CI, CircleCI; the modern engineering norm that compresses release cycles from days to minutes.
17
- Docker
- A platform that packages an app together with all its dependencies into a portable container image. The end of the "works on my machine" problem; the standard artefact of CI/CD and the substrate of Kubernetes and modern PaaS.
18
- Kubernetes
- An orchestration platform that auto-distributes, scales and self-heals containers across hundreds-to-thousands of machines. EKS, GKE, AKS are the managed flavours; the de facto standard for microservice-based production — but overengineered for small teams.
19
- Infrastructure as Code (IaC)
- Managing servers, networks, DBs and cloud resources through versioned code files (Terraform, Pulumi, CloudFormation) rather than manual UI clicks. The foundation of reproducibility, code review, disaster recovery and multi-environment parity.
20
- Observability
- The ability to infer a system's internal state from external signals (metrics, logs, traces — the "three pillars"). Monitoring's evolution: prepares you for unknown-unknowns, not just known-unknowns. Built around Datadog, Grafana + Prometheus, Honeycomb ecosystems.
21
- Distributed Tracing
- Tracking a request's entire journey across frontend → API gateway → microservices → DB → 3rd-party under a single trace ID. OpenTelemetry is the standard; Jaeger, Tempo and Datadog APM are the tooling; the only honest way to root-cause latency in distributed systems.
22
- Event-Driven Architecture
- A paradigm where services publish and consume events rather than calling each other directly. Provides loose coupling + scaling flexibility; Kafka, RabbitMQ, AWS SNS/SQS, Google Pub/Sub serve as backbones; accepts the eventual-consistency tradeoff.
23
- Message Queue
- An intermediary that queues work between producing and consuming systems so it can be processed asynchronously and possibly across machines. RabbitMQ, AWS SQS, Redis Streams; absorbs spikes, adds resilience via retry and dead-letter queues.
24
- BFF (Backend for Frontend)
- A dedicated, optimised backend layer per client type (web, iOS, Android). Shapes data to UI needs and lets the frontend team own it; solves the over-fetching and coupling pain caused by a single overly-generic API.
25
- AWS S3 (Simple Storage Service)
- Amazon's effectively unlimited object-storage service with 99.999999999% (11 nines) durability. Used for static site hosting, image/video CDN origin, data-lake layer and backup targets. Bucket-based with IAM-driven access control.
26
- AWS EC2 (Elastic Compute Cloud)
- AWS's virtual-server (instance) service. 700+ instance types across CPU/RAM/network/GPU dimensions; on-demand, reserved and spot pricing. Auto Scaling Groups + Load Balancers handle horizontal scale; the foundational compute layer in modern stacks before ECS/Fargate/Lambda.
27
- AWS Lambda
- AWS's original and most mature serverless function-as-a-service. You upload code, AWS executes it on events, you pay only for CPU time in millisecond increments. Common event sources: API Gateway, S3, DynamoDB, SQS; Node.js/Python/Go runtimes; cold-start typically 100-300 ms.
28
- AWS VPC (Virtual Private Cloud)
- A private-network isolation in AWS — your virtual data centre where you design IP ranges, subnets, route tables, NAT gateways and internet gateways. The foundation of layered security for production stacks via public/private subnet split + NACLs + Security Groups.
29
- AWS CloudFront
- AWS's global CDN — caches static assets, video and dynamic HTML across 600+ edge locations. Lambda@Edge for request manipulation, native AWS WAF integration, custom domains + ACM SSL; the AWS-stack alternative to Cloudflare.
30
- AWS Route 53
- AWS's DNS + domain-registrar service. Latency-based, geolocation and weighted routing policies enable multi-region failover; health checks + DNS failover automation; alias records bind directly to ELB/CloudFront/S3 (bypassing CNAME limits).
31
- AWS SQS (Simple Queue Service)
- AWS's managed message-queue service. Two flavours: Standard (at-least-once, high throughput) and FIFO (exactly-once, ordered); visibility timeout, dead-letter queue and batch send/receive are standard features. Lambda + SQS is the canonical serverless event-processing pipeline.
32
- AWS RDS (Relational Database Service)
- AWS's managed RDBMS service. PostgreSQL, MySQL, MariaDB, Oracle, SQL Server and Aurora flavours; automated backups, multi-AZ failover, read replicas and encryption at rest. AWS handles patching and minor version upgrades; you just write the queries.
33
- GCP Cloud Run
- Google Cloud's serverless container platform. You upload a Docker image, Cloud Run gives you scale-to-zero and an automatic HTTPS endpoint; per-request pricing, sub-second scale up and down. Built on Knative; the GCP equivalent of AWS Fargate + App Runner.
34
- GCP GKE (Google Kubernetes Engine)
- Google Cloud's managed Kubernetes. Two flavours: Standard mode (you manage the nodes) and Autopilot mode (fully managed, pod-based pricing); Anthos extends GKE to multi-cloud Kubernetes.
35
- Firebase
- Google's mobile + web developer platform. Authentication, Realtime Database, Firestore, Cloud Functions, Cloud Messaging (push), Hosting, Analytics and Crashlytics in a single SDK; the fastest path to a production-ready stack for an MVP without writing a backend.
36
- Azure Functions
- Microsoft Azure's serverless function-as-a-service. C#, JavaScript, Python, Java and PowerShell runtimes; HTTP, timer, blob, event-grid and service-bus triggers; Consumption (pay-per-use) and Premium (always-on, VNet) plans.
37
- Azure App Service
- Microsoft Azure's PaaS for web apps + APIs. Runtimes for .NET, Java, Node.js, Python and PHP; Docker container support; auto-scale, slot-based blue-green deployment, custom domains + free SSL; the enterprise equivalent of Heroku.
38
- IaaS (Infrastructure as a Service)
- The lowest-level cloud service model: virtual servers, networks, storage and IAM are consumed raw, while OS + application sit on top of you. Canonical examples: AWS EC2, GCP Compute Engine, Azure VM. Maximum control, highest operational burden.
39
- PaaS (Platform as a Service)
- The middle tier of the cloud model: OS, runtime, scaling and networking are managed by the provider; you just upload the application. Canonical examples: Heroku, Vercel, Netlify, Azure App Service, Cloud Run. Lowest operational burden, highest vendor lock-in.
40
- SaaS (Software as a Service)
- The top tier of the cloud model: a finished, browser-delivered application served straight to the end user. Classic examples: Salesforce, Slack, Notion, Figma, Google Workspace. Subscription pricing, multi-tenant architecture, zero installation cost.
41
- Multi-cloud
- A strategy that consumes services from more than one cloud provider (AWS + GCP, Azure + AWS). Reduces vendor lock-in and meets region/regulation requirements; in return raises operational complexity and inter-cloud network cost. Anthos, Crossplane and Pulumi are common orchestrators.
42
- Cloud-native Architecture
- The principle of designing an app from day one to consume cloud services (containers, microservices, managed DBs, serverless, observability stack). The CNCF (Cloud Native Computing Foundation) ecosystem is the reference; the polar opposite of a lift-and-shift approach.
43
- Helm
- Kubernetes's package manager — bundles dozens of YAML manifests (Deployment, Service, Ingress, ConfigMap) that form an app into a single parameterised, versioned "chart". helm install / upgrade / rollback enables safe releases to the cluster; a standard tool in modern CD pipelines.
44
- Argo CD
- A GitOps-driven continuous-deployment tool for Kubernetes. The Git repo is the single source of truth; Argo CD continuously watches the cluster and syncs whenever manifests drift. Self-healing, drift detection, multi-cluster deployment and RBAC make it a modern platform-engineering staple.
45
- Kustomize
- A template-free overlay tool for customising Kubernetes manifests (built into kubectl). You define patches per environment (dev/staging/prod) without copying the base manifest. Declarative configuration management without Helm's template complexity.
46
- Service Mesh
- An infrastructure layer that manages traffic between microservices. A sidecar proxy (Envoy) is injected into each service; mTLS, retries, circuit breakers, traffic splitting and observability are managed from one place. Service code stays free of network concerns.
47
- Istio
- The most widely deployed service mesh on Kubernetes. Envoy proxy + a control plane (istiod); mTLS by default, traffic policies (canary, weighted routing), authorisation policies and distributed-tracing integration. Often perceived as complex, which is why Linkerd is a popular alternative.
48
- Postmortem
- A thorough analysis document written after an incident. Timeline, root cause, impact, resolution, action items — must be blameless: the goal is systemic improvement, not finding individuals to blame. A core practice of any learning organisation.
49
- Runbook
- A step-by-step action guide for a specific incident or operational scenario. E.g. "if DB read-replica lag > 30s, do X, run Y." Walks an on-call engineer through the right move at 2 a.m.; alerts linked to runbooks dramatically reduce MTTR.
50
- GitOps
- A deployment paradigm where Git is the source of truth for both infrastructure and application state. Every change ships via PR + merge; an agent (Argo CD, Flux) continuously reconciles the cluster toward Git. Automatic audit trail, rollback as simple as git revert.
51
- Container Registry
- A central server that stores Docker images. Public: Docker Hub, ghcr.io. Private: AWS ECR, GCP Artifact Registry, Azure ACR, Harbor. The middle layer of CI build → registry push → CD pull deployment; image signing + vulnerability scanning are critical.
52
- Chaos Engineering
- A discipline of intentionally injecting failures into production to test resilience. Popularised by Netflix's Chaos Monkey; answers questions like "what happens if a random instance dies?". Surfaces failure modes early by simulating real incidents.
53
- SRE (Site Reliability Engineering)
- A discipline introduced by Google in 2003 that solves ops with software-engineering methods. Built on toil automation, SLO + error budget, postmortem culture and on-call rotation. Often described as "one specific implementation of DevOps".
54
- Blue/Green Deployment
- A deployment strategy that keeps two mirror production environments (blue: live, green: new release) and flips the load balancer to the new one in a single move. Instant rollback on issues; database migrations need care; zero downtime.
55
- Canary Release
- A strategy that exposes a new version to a small slice of users first (e.g. 5%) while monitoring metrics. If error rate or latency degrade the rollout halts; if not, the rollout grows gradually to 25-50-100%. Tools like Argo Rollouts and Flagger automate it.
56
- React Native
- Meta's framework for shipping iOS + Android apps from a single JavaScript codebase. Renders native UI components through a JS bridge / JSI; reuses web React skills on mobile. Used by big apps like Instagram, Discord and Shopify.
57
- Flutter
- Google's UI framework that ships iOS + Android + web + desktop from a single Dart codebase. Renders its own pixels via Skia (now Impeller) on every platform, yielding fast, consistent, highly custom-designed apps.
58
- SwiftUI
- Apple's declarative UI framework for iOS/macOS/watchOS/tvOS, introduced in 2019. Replaces UIKit's imperative state model with view = f(state); preview canvas, animation and dark-mode are integrated. The default choice for new Apple projects.
59
- Kotlin
- A modern JetBrains language fully interoperable with Java on the JVM. Android's officially preferred language since 2017; null safety, coroutines, data classes, sealed classes. With Kotlin Multiplatform (KMP) it can also share code with iOS.
60
- Jetpack Compose
- Google's modern Kotlin-based declarative UI toolkit for Android. @Composable functions replace XML layouts, bringing the SwiftUI mental model to Android. Material 3, animation and accessibility are integrated; recommended for new Android projects.
61
- App Store Connect
- Apple's portal for publishing iOS apps to the App Store. Single dashboard for build uploads, metadata + screenshots, IAP pricing, TestFlight beta distribution, App Review submission, financial reports and sales analytics.
62
- TestFlight
- Apple's service for distributing iOS apps to internal/external testers before they hit the App Store. Up to 10,000 external testers for 90 days, instant feedback collection and automatic crash reporting. The default tool in any iOS beta workflow.
63
- Push Notification
- A system that delivers messages to mobile/desktop users even when the app is closed. APNs (Apple) and FCM (Google) are the platform providers; marketing layers like OneSignal and Braze add segmentation, scheduling and A/B testing. The primary re-engagement channel.
64
- Deep Linking
- A technique that lets a URL open a specific screen in a mobile app. Works via custom URL schemes (myapp://) or modern Universal/App Links. Essential for taking an email/SMS campaign click into a product-detail screen and for attribution.
65
- Universal Link / App Link
- Apple's (Universal Links) and Google's (App Links) modern deep-linking technology that routes regular HTTPS URLs straight to the relevant screen in the native app. If the app is missing, the web URL is the fallback. Closes the security holes of custom URL schemes.
66
- ProGuard / R8
- Tools in the Android build pipeline that minify, obfuscate and shrink code. R8 replaced ProGuard from AGP 3.4 onwards; strips unused classes/methods, shortens names, cuts APK size by 30-50% and makes reverse-engineering harder.
67
- Android App Bundle (AAB)
- Google Play's new distribution format, mandatory since 2021. A single .aab carries every language/DPI/ABI variant; Play Store derives a device-specific split APK. Download size is typically 15-30% smaller than a universal APK.
68
- gRPC
- Google's high-performance RPC framework built on HTTP/2 + Protocol Buffers. Strictly typed contracts (.proto), bidirectional streaming and multi-language code-gen. Roughly 5-10× faster than JSON/REST for internal microservice traffic.
69
- OpenAPI / Swagger
- An open standard for describing REST APIs in machine-readable YAML/JSON schemas. From the schema you can auto-generate Swagger UI docs, mock servers and client SDKs (TypeScript, Python, Go…). The cornerstone of API-first development.
70
- GraphQL Federation
- An architecture for composing multiple GraphQL services into a single "super-graph". Apollo Federation v2 + Router is the reference implementation. Lets microservice teams develop independently while exposing a single API to clients through a central gateway.
71
- WebSocket
- A protocol that carries full-duplex (two-way) communication over a single TCP connection. Starts with an HTTP upgrade, then runs as low-latency messaging. The foundation of real-time chat, live sports scores, collaborative editors (Google Docs) and trading platforms.
72
- SSE (Server-Sent Events)
- A protocol that streams data one-way (server → client) over HTTP using the text/event-stream MIME type. Simpler than WebSocket, with built-in reconnection and proxy/firewall friendliness. Ideal for stock tickers, log streaming and AI chat token streaming.
73
- Long Polling
- The browser opens a long-lived HTTP request to the server; the server responds when new data arrives and the client immediately re-opens. An older near-real-time pattern that predates WebSocket; still used in legacy systems and strict corporate-proxy environments.
74
- API Rate Limiting
- A mechanism that caps how many requests an API consumer can issue in a given time window. Token-bucket, leaky-bucket and fixed-window algorithms; the API returns 429 Too Many Requests + a Retry-After header. Foundational for DoS protection and fair sharing.
75
- Webhook
- A "reverse API" mechanism in which one service POSTs HTTP to another when an event occurs. Stripe payments, GitHub commits, Shopify orders — all delivered as webhooks in real time. A safe implementation requires signed (HMAC) payloads and idempotency keys.
76
- API Gateway
- A single entry point in front of backend microservices. Authentication, rate limiting, request routing, transformation, caching and observability live in one layer; the API surface stays simple for clients. AWS API Gateway, Kong, Apigee and Tyk are common implementations.
77
- Blockchain
- A distributed ledger in which cryptographically signed blocks of transactions are appended in chronological order. Instead of one mutable database, every participating node holds a copy; a consensus algorithm (PoW, PoS) keeps everyone honest. Popularised by Bitcoin in 2009 and the foundation of Web3, NFT and DeFi.
78
- Smart Contract
- Code on a blockchain that runs automatically and self-executes when conditions are met. Ethereum popularised it in 2015 with the EVM (Solidity); lawyer-less escrow, automatic token transfers, NFT minting and DeFi swap logic all live in smart contracts. A bug means losing millions (DAO hack 2016, Ronin 2022).
79
- NFT (Non-Fungible Token)
- A token that is unique and not interchangeable with another — one bitcoin equals another, one NFT does not. Built on ERC-721 / ERC-1155 standards; used wherever provable ownership is needed: art (CryptoPunks, BAYC), in-game items, music royalties, tickets.
80
- ERC-20 / ERC-721 / ERC-1155
- Ethereum's three core token standards: ERC-20 is fungible (money-like — USDC, UNI), ERC-721 is non-fungible (each token unique, classic NFT) and ERC-1155 is multi-token (both fungible and non-fungible inside one contract — ideal for games). Newer standards (ERC-4626 vaults, ERC-6551 token-bound accounts) keep extending the ecosystem.
81
- Crypto Wallet (Custodial vs Non-custodial)
- A custodial wallet (Coinbase, Binance) keeps the keys for you — easy but "not your keys, not your coins". Non-custodial (MetaMask, Phantom, Rabby, Ledger) leaves the seed phrase with you — full control, but one mistake means total loss. For Web3 the standard is non-custodial.
82
- Seed Phrase / Mnemonic Phrase
- A 12-24-word human-readable form of a wallet's private key (BIP-39). Whoever writes it down and stores it safely can recover the wallet from any device; whoever steals it takes all the funds. Never store it digitally, never screenshot it — a metal backup plate is recommended.
83
- DeFi (Decentralized Finance)
- An ecosystem of financial services running on smart contracts with no bank intermediary. Lending (Aave, Compound), DEXs (Uniswap, Curve), derivatives (dYdX, GMX) and stablecoin issuance (Maker DAI). KYC-free, 24/7 and programmable — but smart-contract bugs and regulation are real risks.
84
- DEX (Decentralized Exchange)
- An on-chain swap exchange that runs on liquidity pools instead of an order book. Users trade directly from their wallets, so custody is never given up. Uniswap (Ethereum), PancakeSwap (BNB), Raydium (Solana) and Curve (stablecoin pools) are the leading examples.
85
- AMM (Automated Market Maker)
- An on-chain trading mechanism that prices via a math formula (most often x*y=k) instead of an order book. Liquidity providers deposit two tokens and earn a share of every swap fee. Uniswap V2 (classic), V3 (concentrated liquidity) and V4 (hooks) form the DeFi revolution.
86
- Yield Farming
- A strategy that deposits tokens into DeFi protocols (lending, AMM, staking) to earn rewards. Annual yields (APY) swing from 5% to 1000% but come with traps — impermanent loss, smart-contract risk and token devaluation. The fuel behind the 2020 "DeFi Summer" boom.
87
- Staking
- Locking up tokens on a Proof-of-Stake blockchain to gain validator block-verification power and earn rewards. Ethereum 2.0 staking requires 32 ETH; liquid-staking protocols like Lido and Rocket Pool remove the minimum. Economically, it's how the network's security is funded.
88
- Gas Fee
- The network fee paid to execute a transaction on chains like Ethereum. Measured in gwei (10⁻⁹ ETH); the price depends on smart-contract complexity and network congestion. EIP-1559 introduced a base-fee + tip model in 2021; L2s drop gas costs by ~100×.
89
- L1 vs L2 (Layer 1 / Layer 2)
- L1 is the base blockchain (Ethereum, Bitcoin, Solana); L2 is a second layer built on top of an L1 to scale it (Arbitrum, Optimism, zkSync, Polygon zkEVM, Base). L2s cut transaction cost ~100×, drop latency and inherit security from the L1.
90
- Optimistic Rollup
- An L2 scaling technique that batches transactions off-chain and posts a single summary hash to the L1, assuming "valid unless proven otherwise". A 7-day challenge window applies (withdrawals must wait). Arbitrum, Optimism and Base run on this model.
91
- ZK Rollup (Zero-Knowledge Rollup)
- A modern L2 model widely seen as the successor to Optimistic Rollups — each batch generates a Zero-Knowledge cryptographic proof posted to the L1, so verification is instant and there's no withdrawal wait. zkSync Era, Polygon zkEVM, Starknet and Linea are examples. The long-term winner of the Ethereum roadmap.
92
- DAO (Decentralized Autonomous Organization)
- An organisation governed on-chain by rules encoded in smart contracts. Token holders write and vote on proposals; the code auto-executes the result. Uniswap, Maker, ENS, Aragon and Snapshot voting are key examples. The "company without a CEO" vision — though in practice bureaucratic friction is real.
93
- Tokenomics
- The economic design of a crypto project's token — total supply, allocation across team / investors / community, unlock schedule, inflation rate, utility (governance, staking, fees) and buyback/burn mechanics. Without sound tokenomics, even great technology collapses into project failure.
94
- Stablecoin
- A crypto token pegged to a fiat currency (usually USD). Three main types: fiat-backed (USDT, USDC), crypto-collateralised (DAI) and algorithmic (UST — collapsed in 2022). Critical for on-chain payments, the quote side of DeFi pairs and exchange unit-of-account. Total supply exceeded $200 B in 2024.
95
- IPFS (InterPlanetary File System)
- A peer-to-peer protocol for hosting files across nodes instead of a central server. Content-addressing (a CID hash) means the same file has the same CID on any node. Critical for NFT metadata and decentralised web storage; Filecoin layers economic incentives on top.
96
- Soulbound Token (SBT)
- A non-transferable NFT type Vitalik Buterin proposed in 2022. Designed to carry person-specific data — a university degree, KYC status, on-chain reputation, event attendance. Tokens that can't be sold on an NFT marketplace and that may become Web3's identity infrastructure.
97
- MEV (Maximal Extractable Value)
- Extra profit validators or searchers extract by reordering pending transactions in the mempool. Typical vectors: sandwich attacks, front-running, back-running. On Ethereum it runs into billions of dollars a year; MEV-relays such as Flashbots try to bring transparency to the market.
98
- Account Abstraction (ERC-4337)
- A 2023 mainnet standard that lets Ethereum users run smart-contract wallets instead of plain EOAs (Externally Owned Accounts). Brings social recovery, gas sponsorship, multi-sig, batched transactions and biometric auth — freeing users from seed-phrase trauma. The key to mass adoption.
99
- Game BaaS (PlayFab, Nakama, GameLift)
- Backend-as-a-Service for games: accounts, leaderboards, matchmaking, cloud save, IAP receipt validation, server hosting and anti-cheat behind a single SDK. Microsoft PlayFab, AWS GameLift, Heroic Labs Nakama, Photon Engine and Unity Gaming Services lead the space. The secret behind indie scale.
100
- Game Engine (Unity / Unreal / Godot)
- The software foundation of game development. Unity (C#, dominant on mobile and 2D, $2K+/seat), Unreal Engine (C++ + Blueprint, AAA and photoreal, 5% royalty) and Godot (open-source, GDScript, indie favourite). As of 2024 about 70% of mobile games run on Unity and 50% of AAA on Unreal.
101
- Server Tick Rate
- How many times per second a multiplayer game server recomputes state. CS:GO runs at 64 tick (default) or 128 tick (premium), Valorant at 128 tick, Call of Duty Warzone at 20 tick. Lower tick rate causes input delay and rubberbanding; higher tick rate scales server cost exponentially.
102
- RTP (Real-Time Payments)
- A modern payment rail that delivers 24/7 inter-bank transfers within seconds. The Clearing House RTP and FedNow (2023) in the US; Pix in Brazil; UPI in India; SEPA Instant in Europe; FAST in Turkey. Versus legacy ACH or SWIFT it settles in seconds rather than hours.
103
- ACH (Automated Clearing House)
- The US electronic inter-bank transfer network (1974). Used for payroll, bill pay, B2B transfers and direct debit — high volume, low urgency. Settlement is 1-3 business days at $0.20-1 per transaction. Despite the rise of RTP and FedNow, ACH still dominates with 30 B+ transactions a year in 2024.
104
- SEPA (Single Euro Payments Area)
- A framework that standardises euro-denominated transfers across 36 European countries. SEPA Credit Transfer is the standard rail (T+1), SEPA Instant runs 24/7 in 10 seconds and SEPA Direct Debit handles pull payments. A single IBAN + BIC format; the backbone of European B2B/B2C payments with minimal fees.
105
- SWIFT (Society for Worldwide Interbank Financial Telecommunication)
- A messaging network linking 11,000+ banks and financial institutions internationally. SWIFT itself moves no money; it carries MT103 / MT202 / ISO 20022 messages while the actual transfer settles via correspondent banking. Rivals include China's CIPS, Russia's SPFS and emerging CBDC rails.
106
- Open Banking (PSD2)
- EU regulation (2018) that authorises a bank customer to share their data — and payment initiation rights — with third-party fintechs. PSD2 created AISP (account info) and PISP (payment initiation) licences; with UK Open Banking and EU PSD3 (2024-25) under way, the sector is growing into a $100 B+ market.
107
- Banking-as-a-Service (BaaS)
- A model in which a licensed bank exposes its APIs and infrastructure so fintechs and SaaS companies can offer financial services inside their own products. Stripe Treasury, Unit, Synapse and Solaris (Europe) bring compliance, KYC, ledger, card issuing and account creation behind a single API. The plumbing under the fintech wave.
108
- ISO 20022
- The next-generation XML/JSON-based standard for financial messages. Officially replacing SWIFT MT messages in 2025; richer payloads with structured debtor/creditor metadata and remittance data, plus better fraud detection. SEPA Instant, FedNow, Pix and UPI are all built on ISO 20022.
109
- Green Hosting
- A web-hosting model where data centres run on 100% renewable energy and the company certifies itself as carbon-neutral. The Green Web Foundation tracks 100K+ green-certified hosts; Cloudflare, GreenGeeks, Kualo and A2 Hosting are popular. The first place the Sustainable Web Manifesto gets applied.
110
- 00 Roibase
- The boutique digital marketing agency everyone dreams of working with.
111
- DORA Metrics
- The four engineering-performance metrics published by Google's DevOps Research & Assessment team: Deployment Frequency, Lead Time for Changes, MTTR (Mean Time to Restore) and Change Failure Rate. "Elite" teams deploy daily, restore in under an hour and keep change-failure below 5%.
112
- Internal Developer Platform (IDP)
- An internal platform layer that gives developers self-service environments, deployments, observability and secret management. Combines "deploy this repo, watch logs, manage envs" behind one UI. Backstage, Humanitec and Port lead; the deliverable of modern platform engineering.
113
- Backstage (Spotify)
- The most-used IDP framework, open-sourced by Spotify in 2020. Service catalog, software templates, TechDocs, scaffolder and a plugin marketplace; Spotify, Netflix, American Airlines and Expedia all use it. The de-facto reference for modern platform engineering.
114
- Golden Path
- The official, shortest and safest answer inside a company to "how do I set up a new service, deploy it and observe it?". Lives as Backstage scaffolder templates, Helm charts and opinionated CI pipelines; the experience is "follow these steps, hit MVP with the fewest decisions".
115
- Platform Engineering
- A discipline that builds an internal product-as-platform to free software teams from "DevOps everything is everyone's job". Goals: developer self-service, lower cognitive load and standardisation. Mainstream since 2023 per CNCF, ThoughtWorks and Gartner.
116
- Lead Time for Changes
- The time it takes for a single code commit to reach production. One of the DORA metrics — hours for Elite teams, weeks or months for Low performers. Reduced through CI/CD optimisation, trunk-based development and feature flags.
117
- Cycle Time (Engineering)
- The time from when an issue moves to "in progress" until it closes. The core metric of JIRA, Linear and GitHub Projects reports; 2-5 days in healthy teams, 2-4 weeks in struggling ones. The cousin of lead time; surfaces workflow bottlenecks.
118
- Pull Request Metrics
- Measured indicators across a PR's lifecycle: time to first review, review depth, idle time, PR size (lines changed) and merge frequency. LinearB, Pluralsight Flow, Swarmia and GitHub Insights report on them; healthy PRs average 200-300 lines and merge within 24 hours.
119
- Code Review Time
- The time between opening a PR and getting review approval. Under 4 hours is ideal, 24 hours is acceptable and 3+ days is toxic. Reduced by a CODEOWNERS file, a dedicated reviewer rotation and AI-powered review (CodeRabbit, GitHub Copilot Code Review).
120
- Pre-commit Hook
- A script Git runs automatically before a commit. Handles lint, format, type-check, secret-scan and conventional-commit checks; lives in .git/hooks/pre-commit. The classic combo is Husky + lint-staged + commitlint — the first line of defence against bad code reaching CI.
121
- Husky
- The standard tool in the JavaScript ecosystem for managing Git hooks as an npm package. Hook scripts live in a .husky/ folder, so every developer gets the same pre-commit / pre-push experience. v9's modern config covers commit-msg lint, branch-name checks and no-typeerror gates.
122
- Conventional Commits
- A standardised prefix syntax for commit messages — feat:, fix:, chore:, refactor:, docs:, test:, perf:, ci:. The foundation for semantic-release version automation, auto-generated changelogs and breaking-change detection. Linted with commitlint and gated via pre-commit hook.
123
- Semantic Versioning (semver)
- A version-numbering standard in the MAJOR.MINOR.PATCH form. MAJOR for breaking changes, MINOR for backward-compatible features and PATCH for bug fixes. The basis of dependency resolution in npm, cargo and pip; semantic-release auto-bumps versions from commit messages.
124
- Changeset / Changesets
- A tool from Atlassian and Vercel for managing versions and changelogs of multiple packages in a monorepo. Devs add a changeset markdown file in their PR; on merge it auto-bumps versions, generates the changelog and publishes to npm. The standard in the Turborepo and Nx ecosystem.
125
- Monorepo Tooling (Nx / Turborepo / Lerna)
- Build-orchestration tools that make it easy to manage multiple packages and apps in a single repo. Nx (Nrwl, batteries-included, ML-driven cache), Turborepo (Vercel, fast and simple) and Lerna (the older standard). Affected-only builds, remote cache and parallel execution are critical features.
126
- Workspace (npm / pnpm / yarn)
- A native feature for managing several sub-packages under a single package.json. pnpm workspaces are the fastest (hard-link based); yarn workspaces are the classic; npm workspaces shipped with v7. Brings symlink optimisation, a shared lockfile and one-command cross-package scripts.
127
- AI Pair Programming (Copilot / Cursor / Cline)
- Writing code alongside an LLM inside a code editor. Options include GitHub Copilot (autocomplete + chat), Cursor (Claude/GPT-4 native IDE), Windsurf, Cline (agentic), Tabnine and Codeium. Boosts modern developer productivity by 30-50% and kicked off the AI-native development era.
128
- PagerDuty / Opsgenie (On-Call Tools)
- Platforms for managing on-call rotations, alert routing, escalation policies and incident response. PagerDuty leads, with Atlassian Opsgenie, FireHydrant, Squadcast and Rootly close behind. Avoids alert fatigue and "wakes the right person at the right time"; the SRE's daily toolkit.
129
- Engineering Velocity
- The composite answer to "how much value is this engineering team producing?". Not just commits or PR count — also cycle time, deployment frequency, scope completion and business outcomes together. Linearity Index, Jellyfish and Code Climate Velocity quantify it.
130
- Trunk-Based Development
- A Git strategy where developers integrate small commits into main/trunk daily (or more often) instead of running long-lived feature branches. The purest form of Continuous Integration; reduces merge conflicts and lifts deployment frequency. With feature flags, it's the standard of modern DevOps.
131
- Feature Flag (Toggles)
- Code that is deployed to production but not yet exposed to end users — toggled on or off at runtime. LaunchDarkly, Statsig, Unleash, GrowthBook and Optimizely lead. Indispensable for trunk-based development and the foundation of canary releases, gradual rollouts, A/B tests and kill switches.
132
- Build Pipeline Time
- Total runtime of a CI pipeline. Under 5 minutes is healthy, 5-15 is acceptable and over 30 minutes kills developer velocity. Reduced via caching, parallel jobs, test sharding, affected-only builds and infrastructure optimisation. Directly drives PR turnaround time.
133
- Linter (ESLint / Prettier / Biome)
- Tools that catch code-style issues and likely bugs through static analysis. ESLint (rules + plugins, the JS/TS standard), Prettier (an opinionated formatter) and Biome (a Rust-based modern alternative, ~100× faster). Wired into the dev workflow via pre-commit hooks and IDE plugins; gives consistency and bug prevention.
134
- Test Sharding
- A technique that splits the test suite into small parallel pieces. Breaking 10,000 tests into 10 shards runs them 10× faster. Jest, Vitest, Playwright and Cypress support sharding natively; CI runners like GitHub Actions matrix and CircleCI parallelism enable it. The fastest single win for build-time reduction.
135
- Path Aliases (TypeScript / Vite / Webpack)
- Defining clean import paths like "@/components/Button" instead of "../../../components/Button". Configured in tsconfig.json paths, vite.config.ts resolve.alias and webpack resolve.alias. Improves refactor safety, readability and IDE auto-import; standard in modern monorepo, Nuxt and Next ecosystems.
136
- Error Budget Alerting
- An alerting system that watches how fast an error budget — the inverse of an SLO — is being consumed. A burn-rate alert says "10% of the 30-day budget burnt in 1 hour → page on-call". Multi-window multi-burn-rate alerts (Google SRE Workbook) are the modern standard; they catch real incidents without alert fatigue.
137
- CI Cache (GitHub Actions / CircleCI / GitLab)
- A mechanism that stores the output of build steps and reuses it across CI runners. Targets node_modules, pip dependencies, Docker layers, Turborepo remote cache; cuts pipeline time 3-10×. The unsung hero of modern developer productivity.
138
- SoC (System on a Chip)
- A single piece of silicon that integrates the CPU, GPU, RAM, modem, ISP and NPU. The heart of every mobile device — Apple A17, Snapdragon 8 Gen 3, Tensor G4 and MediaTek Dimensity. 5-10× more power- and cost-efficient than separate chips, with a clear size advantage.
139
- NPU (Neural Processing Unit)
- A chip optimised for neural-network inference. Apple's Neural Engine runs at 38 TOPS, with Qualcomm Hexagon and Google Tensor TPU close behind; critical for on-device LLMs, computer vision and voice transcription. The chip behind iPhone's Live Text, offline Siri and Genmoji.
140
- TPU (Tensor Processing Unit)
- An ASIC Google designed in 2016 for TensorFlow, optimised for matrix multiplications. The v5p (2024) hits 459 TFLOPS at bf16, and a Google Cloud TPU pod with 8,000+ chips delivers 8 zettaflops a year. For GPT-class LLM training it sits beside NVIDIA H100 as the two main options.
141
- Apple Silicon (M-series)
- Apple's 2020 move from Intel to its own ARM-based chips — M1, M2, M3 and M4 — across Mac, iPad Pro and Vision Pro. Unified memory architecture, performance plus efficiency cores. Brought Macs to mobile-grade power draw and is competitive on LLM workloads.
142
- RISC-V
- An open-source instruction-set architecture from UC Berkeley (2010). No licence fees and free custom extensions; Western Digital, NVIDIA, SiFive and Alibaba (XuanTie) lead the way. China's preferred route around US chip sanctions and the modular, royalty-free rival to ARM.
143
- MCU (Microcontroller Unit)
- A low-power microcontroller that puts CPU, flash, RAM and I/O on one chip. ARM Cortex-M, ESP32, STM32 and Arduino are the staples; lives in watches, sensors, smart-home devices and automotive ECUs. Power draw in the mW-µW range, cost $0.50-5 — the building block of IoT.
144
- ONNX Runtime
- Microsoft's cross-platform inference engine for the Open Neural Network Exchange format. Lets you export PyTorch or TensorFlow models to ONNX and run them on CPU, GPU, NPU, mobile, browser (WebAssembly) or edge devices. The "USB-C" of AI deployment.
145
- Core ML (Apple)
- Apple's on-device ML framework for iOS and macOS. Object detection, NLP, image segmentation and speech-recognition models run optimised on the Neural Engine; coremltools converts PyTorch or TensorFlow models into .mlpackage. The AI secret of iOS apps.
146
- TensorFlow Lite
- Google's mobile and edge-optimised TensorFlow variant. Supports the Android Neural Networks API, iOS Metal, Edge TPU and Coral devices; .tflite files are 1-100 MB. Quantisation (int8 or float16) shrinks the model up to 4×.
147
- MQTT
- A lightweight publish-subscribe messaging protocol optimised for IoT. Designed to run on low-bandwidth, high-latency networks; brokers like Mosquitto, HiveMQ, AWS IoT Core and EMQX let millions of devices exchange messages at once.
148

Runs over Wi-Fi, Thread or Ethernet; lets Apple Home, Google Home, Alexa and SmartThings control devices across ecosystems. The first serious answer to the "IoT Babel" problem.
151
- Thread (IoT Mesh)
- A low-power IPv6-based mesh network protocol (Nest 2014, run by the Thread Group). Builds a self-healing mesh between smart-home devices and runs underneath Matter. Uses up to 100× less power than Wi-Fi; the Apple HomePod and Google Nest hubs act as Thread border routers.
152
- Zigbee / Z-Wave
- Classic smart-home mesh network protocols. Zigbee uses 2.4 GHz (Philips Hue, the Hue Bridge, IKEA Trådfri); Z-Wave uses 800-900 MHz with better wall penetration but is proprietary. Both have entered a transitional phase as Matter rises; backward compatibility still matters.
153
- LoRaWAN
- Long Range Wide Area Network — an ultra-low-power sub-GHz IoT protocol with 10-15 km range. Used in smart agriculture, asset tracking, smart cities and smart meters; a battery-powered device can run for years. The Things Network gives free global community-network infrastructure.
