I will fix bugs and performance issues in dot net web app
Ali
About this gig
Struggling with a stubborn bug or slow-performing .NET application?
I can help.
I'm a full-stack .NET developer with hands-on experience across ASP.NET Core, ASP.NET MVC, Blazor, and Web API plus the front-end side (Angular, React) and database layer (SQL Server, Entity Framework). Whatever's broken, I'll dig in to find the actual root cause, not just patch the symptom.
What I handle:
- Bug fixes in ASP.NET Core / MVC / Blazor applications.
- Performance issues (slow queries, memory leaks, high load times).
- SQL Server / Entity Framework errors.
- Angular/React front-end issues tied to a .NET backend.
- Production incidents that need a fast, safe fix.
Before ordering: send me your error message, framework/version, and a short description of the issue. I'll confirm I can fix it and give you an accurate timeline usually within a few hours.
Message me first for anything beyond a single quick fix, so we can scope it properly before you order.
