About this gig

Need a reliable .NET developer for a small task?

I'm a .NET developer with 10+ years of experience in HR/finance/admin systems. I specialize in C#, ASP.NET Core, and SQL Server, and I deliver clean, tested code with clear documentation.


What I can help with:

  • Bug fixes in C# / ASP.NET Core / .NET Framework
  • Small feature additions to existing web apps or APIs
  • SQL query optimization
  • Code review and refactoring suggestions


What you get:

  • Fixed/working code committed to your repo (or delivered as a zip)
  • Brief English summary of what was changed and why
  • One round of revisions included


Before ordering: Send me your repo link or code snippet and describe the issue. I'll confirm scope before starting.


I respond within 24 hours. Async communication preferred.
