About this gig

Got a bug that won't die? I'll find it and fix it properly.

I'm a senior .NET developer and I diagnose bugs at the root cause instead of taping over the symptom. Send me your issue and I'll tell you honestly whether I can fix it and how long it'll take.


I can help with:

  • Runtime errors, exceptions, and crashes
  • Logic bugs and incorrect output
  • API, database, and integration issues
  • Async / threading and performance problems
  • ASP.NET Core, Web API, console & desktop apps

What you get: a working fix, a plainEnglish explanation of what was wrong, and (on higher tiers) a test so it stays fixed.


Please message me first with a description of the bug, any error messages, and your code or repo access. That lets me quote accurately and start fast.

Clear communication, quick turnaround, and no vanishing acts. Let's get your code

I'm a senior software developer with years of hands‑on experience building and shipping production software in C# and .NET. I specialize in backend and API development, and I work across the full stack with JavaScript and React when a project needs it. What you get working with me: clean, readable code, clear communication, and honest timelines. I don't disappear — I explain what I'm doing and why. Whether you need a bug hunted down, an API built, or a feature shipped end‑to‑end, I'll treat your codebase like my own. Message me before ordering and I'll tell you honestly if I'm the right fit.
