About this gig

Is your Web API returning unexpected errors, failing requests, authentication issues, or deployment problems? I will quickly identify the root cause and fix your API so it works reliably.

I specialize in ASP.NET Core Web API, REST APIs, and modern backend development. Whether you're facing a small bug or a complex issue, I'll deliver a clean, efficient, and production-ready solution.

  • CORS issues
  • JWT Authentication & Authorization
  • ASP.NET Core Identity
  • Entity Framework Core & SQL Server errors
  • Model binding & validation issues
  • JSON serialization/deserialization
