About this gig

Need a reliable .NET developer to fix a bug or add an API endpoint?


I focus on ASP.NET Core backend development: clean fixes, tested code, and clear explanations.


What I can do:

  • Diagnose and fix backend bugs in ASP.NET Core / .NET
  • - Build REST / minimal API endpoints
  • - Fix Entity Framework Core, SQL Server, or migration issues
  • - Resolve authentication/authorization problems
  • - Add unit/integration tests so the bug does not return

What you get:

  • Source code fix in your repo or as a zip
  • - Explanation of root cause
  • - Test that fails before the fix and passes after
  • - Clean, commented code

Before ordering, send me:

  • Description of the bug or endpoint needed
  • - Access to repo or source files
  • - Steps to reproduce or expected behavior

Note: this gig is for one focused bug or endpoint. Larger features need a custom offer.
