I will fix bugs and issues in your dotnet application
Alessandro
Over deze dienst
Is your C# / .NET application throwing errors, crashing, or behaving in a way that makes no sense?
I'm a .NET developer working on applications running in production not tutorials or demos. Send me the bug, I'll find the root cause and fix it properly instead of patching over it.
What I fix:
Runtime errors, exceptions and crashes
ASP.NET Core / Blazor issues (routing, auth, DI, state)
Entity Framework Core & SQL Server problems queries, migrations, performance
REST API bugs and integration issues
WPF / desktop application bugs
Deployment issues (IIS, Linux + Nginx)
What you get: a working fix, plus a clear explanation of what was broken and why so it doesn't come back.
What I need from you: access to the source code, the error message, and the steps to reproduce the bug.
I only work on C# / .NET projects no PHP, Node.js or WordPress.
Please message me before ordering so I can look at the issue and confirm the right package. I'd rather ask a question early than deliver the wrong thing.

I build custom web apps and management systems (CRM/ERP) that help businesses work smarter. Using C# and .NET (Blazor), I handle the whole project — the interface, the secure backend, and the database. You get a clean, reliable product built for you, not a template.
Recent work: a full CRM/ERP system built end to end, with secure login, data management and a modern interface.
Clear communication, honest timelines, and code that lasts. Let's talk about your project.

Veelgestelde vragen
What information do you need to start?
The source code (GitHub, ZIP or repo access), the exact error message or stack trace, and the steps to reproduce the issue. The more context you give me, the faster the fix.
What if I have more bugs than the package includes?
Just add the "Additional bug fix" extra, or message me and I'll send you a custom offer for the whole set.
Do you work with older .NET versions?
Yes .NET Framework 4.x, .NET Core, and .NET 5 through 9. I also handle migrations from legacy .NET Framework to modern .NET.
Will you keep my code confidential?
Yes. Your code stays private and I don't reuse or share it. Happy to sign an NDA if needed.
What if you can't fix it?
I'll tell you before you order if I don't think I can solve it. If I take the job and can't deliver, you get a full refund.
