About this gig
Do your C# / .NET application is experiencing bugs, crashes, or performance issues?
With 13 years of experience and 27+ enterprise systems delivered, I specialize in debugging production applications, identifying root causes, and implementing clean fixes without introducing new issues.
Ive worked on:
ASP.NET / .NET Core / .NET Framework applications
REST APIs and backend services
Desktop applications (WinForms / WPF)
SQL Server performance and query issues
Integration and authentication problems
Typical issues I help resolve:
1-Application crashes or runtime errors
2-Slow performance or memory leaks
3-API failures or integration issues
4-Database query bottlenecks
5-Unexpected system behavior
My approach focuses on identifying the root cause and delivering stable, production-safe fixes, not temporary patches.
