About this gig

Need a reliable backend for your app, or an existing API that isn't working as expected?

I'm a backend developer with 4+ years of professional experience building APIs and data integrations with Python, FastAPI, .NET/C# and SQL.

What I can do for you:

  • Build REST APIs from scratch with FastAPI
  • Fix bugs or add new endpoints to an existing API
  • Connect your API to SQL databases (SQL Server, PostgreSQL, MySQL)
  • Add authentication (JWT) and input validation
  • Write automated tests and clear API documentation (Swagger/OpenAPI)

What you get:

  • Clean, readable and well-structured code
  • Full source code
  • Clear communication and progress updates
  • Support for questions after delivery

Please message me before ordering so we can confirm the scope, number of endpoints and delivery time. This way you get exactly what you need, with no surprises.
