I will investigate and fix bugs in your C# or ASP.NET Core application.

I can work with existing .NET codebases, identify the root cause of an issue, implement a clean fix, and verify that the application works correctly.

What I can help with:

• ASP.NET Core API errors • HTTP 400, 401, 403, 404 and 500 issues • Entity Framework Core problems • PostgreSQL and SQL Server issues • JWT authentication and authorization • Broken endpoints and business logic • Dependency injection and configuration issues • Async and background processing bugs • Third-party API integration errors • Performance and database query issues • Unit and integration test failures

With 16+ years of .NET experience, I can quickly review unfamiliar codebases and focus on the smallest safe and maintainable solution.
