About this gig

Bug in your ASP.NET Core API, or a new endpoint you need done properly? I can help.


- Root cause first: I find why it breaks, not just patch the symptom

- Clean, tested fixes that match your existing code style

- New endpoints with validation (FluentValidation), proper error handling and structured logging

- .NET 6 to .NET 10, minimal APIs, controllers, MediatR, EF Core


I build and maintain production .NET 10 APIs and background workers for a multi-tenant SaaS platform.


Send me the error, the logs or a short description before ordering.
