Debug Our C# Desktop App

Our production-level desktop application is written in C#/.NET and has begun to show a handful of stubborn bugs. I need an experienced troubleshooter to dive into the existing codebase, pinpoint the root causes, apply solid fixes, and validate that every feature still behaves exactly as intended once the patches are in place. You will be working directly in the current repository, so please be comfortable reading someone else’s code, tracing through complex logic, and testing across the full stack of the application. Clean commits, clear comments, and a safety-first mindset (no regressions) are critical. Because we rely on this system every day, I’d like you to: • isolate and repair the reported errors, • run thorough regression tests to confirm nothing new breaks, and • suggest quick wins that improve stability or performance where you spot them. Send a brief note outlining similar debugging projects you have handled, when you can start, and your hourly rate. I am ready to give access as soon as we agree, so availability this week is highly preferred.
