About this gig

Need an ASP NET Core, EF Core, OData, or PostgreSQL API issue fixed? I can debug the problem, explain the root cause, and deliver clean backend code.


I can help with:

- ASP NET Core endpoint bugs, routing, controllers, services, and validation

- EF Core query issues, migrations, PostgreSQL data access, and performance cleanup

- OData filtering, sorting, expansion, and response-shape problems

- Auth related issues, background services, RabbitMQ, Redis, Swagger, and API integration


I have professional experience building .NET 9 APIs with EF Core, OData, PostgreSQL, hosted services, RabbitMQ, Redis, and production-style logging.


For the Basic package, send one clear backend issue with logs, expected behavior, and relevant code or repo access. Message me first if the issue spans multiple modules.
