About this gig

Need help with a .NET project that has bugs, errors, or messy code?

I will fix issues and improve your existing .NET / C# application, focusing on backend, APIs, and maintenance.

What I can help with:

  • Bug fixing and runtime errors
  • ASP.NET MVC and ASP.NET Core troubleshooting
  • Web API endpoints and integrations
  • Entity Framework and SQL related issues
  • Refactoring and code cleanup
  • Performance improvements for slow parts of the app

What I need from you:

  • Source code (Git repo or zip)
  • Clear description of the issue
  • Steps to reproduce (if possible)
  • Error logs or screenshots

What you will get:

  • A working fix (or best possible solution based on available info)
  • Clean, maintainable changes
  • Short summary of what was done

Message me before ordering if you are not sure which package to choose.

  • Programming language

    • ASP.NET
