Awesome-omni-skill backend-development

Build robust backend systems with modern technologies (Node.js, Python, Go, Rust), frameworks (NestJS, FastAPI, Django), databases (PostgreSQL, MongoDB, Redis), APIs (REST, GraphQL, gRPC), authentication (OAuth 2.1, JWT), testing strategies, security best practices (OWASP Top 10), performance optimization, scalability patterns (microservices, caching, sharding), DevOps practices (Docker, Kubernetes, CI/CD), and monitoring. Use when designing APIs, implementing authentication, optimizing database queries, setting up CI/CD pipelines, handling security vulnerabilities, building microservices, or developing production-ready backend systems.

2025 Key Updates

Area	2025 Best Practice
Auth	OAuth 2.1 + PKCE mandatory, Passkeys/WebAuthn
Security	OWASP 2025, Zero Trust Architecture
DB	PostgreSQL 17, pgvector for AI, serverless DBs
Observability	OpenTelemetry standard
Frameworks	Hono, Elysia for edge; Effect-TS for FP
AI Integration	LLMs as probabilistic components

Core Patterns (2025)

API: REST (CRUD) → GraphQL (complex) → gRPC (microservices) → tRPC (TypeScript)

Auth: OAuth 2.1 + PKCE → Passkeys → JWT (short-lived) → Refresh rotation

DB: Connection pooling → Indexing → Read replicas → Sharding

Security: Zero Trust → Input validation → Parameterized queries → Rate limiting

Testing: Unit 70% → Integration 20% → E2E 10% → Contract tests
