Backend APIs & System Architecture
Design and ship clean, scalable REST/WebSocket backends with rock-solid auth, observability, and documentation.
Key Features
- •API design (REST/WebSockets) with OpenAPI 3
- •AuthN/AuthZ (JWT/OAuth2, RBAC/ABAC)
- •PostgreSQL schema + migrations, indexing strategy
- •Caching & performance (Redis, connection pooling)
- •Observability (structured logs, metrics, health checks)
- •CI/CD (GitHub Actions) and env promotion (dev→staging→prod)
Technologies
Overview
I architect and implement production-grade backends using clean architecture (controllers → services → repositories), DTO contracts, and strict typing. You get secure JWT/OAuth2 auth, RBAC/ABAC, database migrations, caching strategy, rate limiting, and a real CI/CD pipeline. Everything ships with OpenAPI docs, load testing, and environment-isolated configs.
