Services
FastAPI Backend Engineering
I build async, scalable REST APIs with Python and FastAPI — from lightweight microservices to multi-service platforms with authentication, background tasks, and cloud deployment baked in from day one.
What I deliver
- Async FastAPI services with full OpenAPI/Swagger documentation
- JWT-based authentication and role-based access control (RBAC)
- MongoDB and PostgreSQL data layers with efficient query patterns
- Background task processing and server-sent event (SSE) streaming
- Docker containerisation and cloud deployment (Vercel, Railway, Render)
- Rate limiting, input validation, and production error handling
