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.
