I will fastapi backend and API development


About this gig
Need a backend that's fast, reliable, and doesn't fall over under load? I build production-grade REST APIs using FastAPI, Python, and PostgreSQL the same stack I use daily as a backend engineer.
In my most recent role, I built a document processing pipeline that delivers structured data in under 3 seconds with sub-100ms response times under concurrent traffic. I've shipped 20+ API endpoints across three companies, covering everything from leave management systems to multi-tenant marketing platforms.
What you'll get:
- Clean, well-documented FastAPI endpoints
- PostgreSQL schema designed for your data, not a generic template
- Proper error handling and input validation
- Basic authentication/authorization if needed
- Deployment-ready code with clear setup instructions
Why work with me: I write code that holds up under real traffic, with the same reliability standards I use in production systems at my day job. I communicate clearly, deliver on time, and I'm available for quick revisions.
Message me before ordering if your project has specific requirements I'll tell you honestly if it's a fit.
