I will fix bugs and add features to your asp net core or dotnet app


About this gig
Need a bug fixed or a feature added to your .NET application? I'm a senior .NET engineer and tech lead with 7 years of backend experience, and I'll fix it properly, not just patch it.
What I can do:
- Fix bugs in ASP.NET Core, Web API, MVC and .NET Framework apps
- Add new features, endpoints and integrations
- Fix EF Core, SQL Server and PostgreSQL issues: slow queries, migrations, data bugs
- Fix login and authorization problems (JWT, OAuth/OIDC)
- Angular front-end fixes connected to a .NET backend
How it works:
1. Message me before ordering with the issue and your .NET version, so I can confirm the scope and price
2. I reproduce the problem, find the root cause and fix it
3. You get the fix as a pull request or code changes, with a short note on what changed and why
Stack: C#, .NET 610 and .NET Framework, ASP.NET Core, EF Core, SQL Server, PostgreSQL, Redis, Azure, AWS, Angular.
I'm happy to sign an NDA, and I work on a copy or staging environment, never directly on your live system.

Which .NET versions do you work with?
.NET Framework 4.x and .NET 6–10, including ASP.NET Core, Web API and MVC.
What if the bug turns out bigger than expected?
I’ll tell you before doing any extra work and send a custom offer for the rest. You only pay for what we agreed.
Can you upgrade my app to .NET 10?
Yes. Message me with the project size and I’ll send a custom offer.
Do you need access to my live server?
No. I work on your repository and a copy or staging environment, so please don’t send production passwords.
