About this gig

Is your ASP.NET Core application crashing, throwing errors, or behaving unexpectedly?


I specialize in debugging and fixing .NET backend issues in existing codebases.

If youre stuck with a bug and need a reliable fix I can help.


What I can help you with:

- Fix runtime errors & exceptions

- Debug ASP.NET Core APIs

- Resolve async/await & threading issues

- Fix EF Core bugs and performance problems

- Investigate crashes and unexpected behavior

- Clean, safe fixes without breaking existing features


Why work with me:

- Strong experience with production .NET systems

- Fast understanding of existing codebases

- Clear explanation of the root cause and solution

- Focus on reliability, not quick hacks


I prefer working on real, existing projects and fixing real problems.


Please message me before ordering so I can review the issue and confirm the scope.
