I will fix bugs and errors in your asp net core and c sharp application

Something in your .NET application is broken and you need it working today. Send it to me.

I am a .NET backend engineer working on production SaaS platforms every day. Debugging is most of that job: race conditions, memory leaks, slow queries, broken auth, deployment failures.

WHAT I FIX

- Runtime errors and unhandled exceptions

- Entity Framework issues, slow queries, migration failures

- Authentication problems: JWT, cookies, roles, CORS

- API bugs, wrong responses, serialisation issues

- Performance problems and memory leaks

- Docker and deployment failures

- Failing or flaky tests

HOW IT WORKS

Send your code and describe what goes wrong. I reproduce the bug first, then fix the cause rather than patching the symptom. You get an explanation of what was actually wrong, so the same bug does not come back.

On Standard and Premium I add a regression test for every fix.

WHAT I WORK WITH

C#, ASP.NET Core, EF Core, PostgreSQL, SQL Server, Redis, SignalR, Docker, Next.js, React.

Message me before ordering with a short description of the problem. I will tell you honestly whether it is a quick fix or a bigger job.
