Project details

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.

I’ve 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.
