About this gig

Is your ASP.NET Core Web API throwing errors, returning 500s, or behaving differently than expected? I'll find the root cause and fix it with minimal, clean changes to your existing code.


Common problems I fix:

  • 500 errors, unhandled exceptions and failing endpoints
  • Entity Framework Core errors, migrations and query issues
  • JWT authentication and 401/403 authorization problems
  • CORS, dependency injection and configuration errors
  • Slow endpoints and inefficient database queries


What you get:

  • A working fix in your codebase
  • A short explanation of what caused the problem and what I changed
  • Testing of the fixed functionality


What I need from you:

  • Source code (repository access or zip)
  • The exact error message or expected behavior
  • Steps to reproduce the problem


Not included: new features, frontend work, or issues outside the agreed scope. These can be added with a custom offer.


Please message me before ordering so I can review your issue and confirm the right package.
