About this gig

Got code that doesn't work, runs slow, or is hard to maintain? I'll review, debug, and clean it up and explain every change so you actually learn from it.


Bug hunting & fixing (logic, syntax, runtime errors)

Refactoring for readability and maintainability

Performance optimization

Adding tests (pytest, Jest, Vitest)

Works with Python, JavaScript, TypeScript, Bash, SQL


Share your code + describe the problem. I'll return fixed, commented code with a written explanation of what was wrong.
