About this gig

Is your .NET app throwing exceptions or returning wrong data? I fix bugs fast and explain exactly what went wrong so it never happens again.

I have 2+ years building live systems for AlBaraka Bank and Bank Al-Makarmah debugging everything from null reference exceptions to transaction deadlocks in real banking environments.

What I fix: 500 errors, broken endpoints, JWT auth failures CORS issues, middleware errors, DI problems Slow SQL queries, stored procedure errors, EF migration failures Dapper mapping issues, connection timeouts, deadlocks Wrong business logic, null exceptions, async deadlocks WinForms UI bugs, LINQ errors, memory leaks

Technologies: ASP.NET Core 4-9, C#, SQL Server, Dapper, Entity Framework, REST APIs, Minimal APIs, WinForms, React + .NET

Every fix includes the corrected code, a clear explanation of the cause, and suggestions to prevent it recurring.

Message me before ordering share your error and I will confirm I can fix it before you pay. I respond within 1 hour, every day.

.NET Backend Developer with 3+ years building production systems for AlBaraka Bank & Bank Al-Makarmah. I've shipped real banking apps handling bulk transactions, role-based access control, and payroll systems — not tutorial projects. I build: REST APIs (ASP.NET Core 6-9), Full-Stack apps (.NET + React, MERN), Desktop apps (WinForms), and high-performance SQL (Dapper, Stored Procedures). Fast communicator. Production mindset. Real results. Let's build something that works — message me anytime.
