I will fix bugs in your c sharp, c plus plus or python code
Zakhar Vlasenko
About this gig
Getting an error you can't get rid of, a crash, or code that gives the wrong result? Send it to me. I find the cause, fix it, and explain in plain words what went wrong.
Languages I work with:
- C#: .NET, WPF, WinForms, ASP.NET Core, Unity scripts
- C++: C++11 to C++20, Qt, CMake, Visual Studio, memory and pointer issues
- Python: scripts, Django, FastAPI, pandas, bots, install and dependency errors
Typical jobs:
- Exceptions, crashes and segfaults
- Build, compile and linker errors
- Wrong output and logic bugs
- Slow code that needs to run faster
- Code that broke after an update or a library change
How it works: send the code (files, zip or a Git repo), the error message and the steps to reproduce it. I look at it and confirm the price before you order, so you only pay for work that can be done.

FAQ
What if you can't fix the bug?
I check your code before you order, so this is rare. If I still can't fix it, I'll explain what I found and we cancel the order through Fiverr so you get your money back.
What do you need from me to start?
The code (zip or Git link), the full error message or a screenshot, the steps that cause the bug, and your setup: operating system, language version and the libraries you use.
Can you work on a large project?
Yes. Share the repo and point me to the part that fails. I focus on the bug and avoid changing code that already works.
Will you explain what was wrong?
Yes. Every delivery includes a short note on the cause of each bug, what I changed, and how to avoid it next time.
Can you fix Unity or Unreal Engine errors?
Yes, C# errors in Unity and C++ errors in Unreal Engine. For new game features rather than fixes, see my game development gig.
