About this gig

Are your users experiencing 500 errors? Is your API lagging, leaking memory, or failing with frustrating CORS issues? Don't waste days debugging.


I am a Backend Engineer specializing in Go (Golang), Node js, and TypeScript. I don't just "patch" bugs; I dive into your codebase, identify the root cause, and deliver a clean, tested fix that won't break again.


What I can fix for you:

- Node.js & Express API crashes or silent failures

- Go concurrency issues (goroutines) & memory leaks

- Database query optimization (PostgreSQL, MongoDB)

- Authentication, JWT, and CORS configuration errors

- Third-party API integration bugs


Why work with me?

I have an async-first mindset. I don't need hand-holding. Give me the repo, explain the issue, and I will deliver the Pull Request quickly and cleanly.


Important: Please send me a message BEFORE placing an order so we can confirm the scope of the bug!
