About this gig

Is your .NET application throwing errors, crashing, or behaving strangely? I've spent 6+ years building and maintaining production ASP.NET Core APIs, so I find the real cause instead of patching symptoms.

I can fix:

  • ASP.NET Core / Web API errors (500s, routing, JWT auth, CORS)
  • Entity Framework issues (migrations, relationships, slow queries)
  • SQL Server / MySQL errors, deadlocks, and slow stored procedures
  • Third-party API integration errors (Stripe, PayPal, webhooks, REST APIs)
  • Dependency injection, configuration, and startup crashes
  • Deployment issues on IIS, Azure, or Linux
  • Code built with AI tools that's stuck and won't work

How it works: Send me the error and your code, and I'll confirm the fix and timeline before you order.
