About this gig

Need a .NET developer to build a new ASP.NET Core Web API or fix a bug in your C# application? I'm a professional .NET backend developer working on enterprise systems, and I deliver clean, secure, production-ready code.


What I can do:

  • Build REST APIs with ASP.NET Core Web API and Entity Framework Core
  • Fix bugs, errors, and slow performance in existing .NET apps
  • Add features to ASP.NET MVC, Web API, or Blazor projects
  • JWT authentication, ASP.NET Identity, and role-based access
  • SQL Server database design, queries, and optimization
  • Migrate .NET Framework apps to .NET 8 / .NET 10
  • Third-party API and payment gateway integration

Why work with me:

  • Real enterprise experience, not tutorial projects
  • Clean architecture, proper error handling, and input validation
  • Fast, scalable code built to handle real traffic
  • Clear communication and on-time delivery
  • Full source code and documentation included

Please message me before ordering with a short description of your project so I can confirm scope and give an accurate delivery time.
