I will fix bugs and optimize performance of your software


About this gig
Is your project almost working but held together by bugs, crashes, or performance issues you cant track down?
I specialize in debugging, fixing, and optimizing existing codebases. Whether its a subtle logic bug, a nasty race condition, or code that just runs far slower than it should, I can help you get things back under control.
I've spent years working on large, real-world systems where correctness, performance, and long-term maintainability actually matter not just it works on my machine.
What I can help with:
- Fixing crashes, logic bugs, and hard-to-reproduce issues
- Improving performance (CPU, memory, I/O, startup time)
- Debugging concurrency, threading, and async problems
- Refactoring confusing or brittle code into something sane
- Root-cause analysis with clear explanations of why it broke
I don't just patch symptoms I focus on understanding the underlying problem.
How this works:
- You share the code (or a minimal repro), the symptoms, and what you've tried
- I investigate and explain what's going wrong
- I deliver a fix, optimization, or patch with notes so you understand it
Feel free to message me first to see if I'm a good fit for solving your problem.

FAQ
What kind of bugs do you fix?
I handle crashes, incorrect behavior, performance regressions, memory leaks, race conditions, and “it sometimes fails” problems. If the issue requires careful debugging or analysis, it’s a good fit.
Can you work with an existing / messy codebase?
Yes — that’s my specialty. I’m comfortable stepping into unfamiliar or poorly-documented code and figuring out what’s really going on.
Do you need full access to my code?
Ideally yes, but I can also work from a minimal reproduction or isolated module if sharing the full codebase isn’t possible.
Will you explain the fix?
Absolutely. I always include a clear explanation of: * what the bug was * why it happened * what was changed So you’re not left guessing later.
Can you guarantee a fix?
Some issues are straightforward; others require investigation. If I believe an issue is outside my scope or not solvable within the gig, I’ll tell you before proceeding.
Is my code confidential?
Yes. I treat all client code as confidential and never reuse or share it.
Should I contact you before ordering?
Yes — especially for complex issues. A quick message helps me confirm scope and give you the best outcome.
