Backend Development

FastAPI Backend Development

High-performance REST and GraphQL APIs built with FastAPI — 100K+ requests/day, sub-200ms response times.

From $2,5002-4 weeks

The problem

Businesses need APIs that handle real traffic without breaking — authentication, rate limiting, database optimization, and documentation are often afterthoughts until production fails.

The solution

I design, build, and ship production-grade FastAPI backends: REST and GraphQL endpoints, JWT auth, PostgreSQL/Redis optimization, async task queues, CI/CD, and monitoring. Built to scale from day one.

Outcome

APIs that handle 100K+ requests/day with sub-200ms response times, comprehensive documentation, and zero-downtime deploys.
