I will debug, fix, and optimize your c sharp dot net backend or API

About this gig
Is your .NET backend throwing errors? Are your API endpoints failing, or are webhooks getting blocked?
Don't let a broken codebase slow down your business. I specialize in backend debugging, API troubleshooting, and resolving network-level communication errors within the C# / .NET ecosystem.
What I can fix for you:
- Logical bugs and runtime exceptions in C#
- REST API routing issues and HTTP 500 errors
- Webhook integration failures (JSON parsing, secret key validation)
- Incoming POST request drops (Cloudflare/WAF block diagnostics)
- Database connection and Entity Framework configuration issues
Why choose me? I don't just patch symptoms; I dive deep into server logs, network requests, and terminal workflows to identify the exact root cause of the problem, ensuring a clean and permanent fix.
Please message me before placing an order so we can discuss the exact issue and look at the logs together!

FAQ
Do I need to contact you before placing an order?
Yes, please message me first. Every bug and system architecture is different. Discussing the error logs and code structure beforehand ensures we choose the right package for your exact issue.
What access do you need to fix the bug?
I will usually need access to the affected source code repository (GitHub/GitLab) or a zip file of the project, along with any relevant error messages or server logs.
Can you fix issues related to third-party APIs or webhooks?
Absolutely. I specialize in tracing API endpoints, resolving network drops, checking payload issues, and diagnosing routing or configuration errors behind Cloudflare and WAF blocks.
Do you write clean, maintainable code?
Yes. I focus on high-quality, readable C# code that follows industry best practices, ensuring that the fix is permanent and doesn't break other parts of your backend.
