I will fix bugs in your cursor, lovable, replit or bolt generated backend
Pavlo Ogurtsov
About this gig
You're in the right place if your Python, Node.js, or Go backend has bugs, crashes, or slows down under load.
I'm Pavlo, a backend developer with 4+ years of experience building and maintaining production APIs and services. I fix issues fast without breaking existing functionality.
What I handle:
- Bug investigation and root-cause fixes
- - Performance bottlenecks and slow queries
- - Memory leaks and crash issues
- - Code review and stabilization before launch
Real experience: fintech, marketplace, and energy-sector backends running in production.
You can count on:
- Clean, documented fixes
- - Clear explanation of what caused the issue
- - Fast, reliable communication (English: B2)
Tools & technologies: Python, Node.js, Go, PostgreSQL, Redis, Docker, Git.
Why hire me: I also work comfortably inside AI-assisted ("vibe coded") projects built with Cursor or Copilot - I can read, fix, and stabilize that code just as fast as hand-written backends.

FAQ
What do you need from me to get started?
Repo access (or a code zip), a description of the bug, and any error logs or reproduction steps. For performance issues, let me know which endpoints or processes are slow.
Which languages and frameworks do you work with?
Python (Django, FastAPI, Flask), Node.js (Express, NestJS), and Go. Databases: PostgreSQL, MySQL, MongoDB, Redis. Comfortable in Docker-based and cloud (AWS) environments.
Will I understand what caused the bug?
Yes. Every fix comes with a clear explanation of the root cause and documentation of the change, so you know exactly what was wrong and how it was resolved.
Can you work on a live production system?
Yes. I reproduce the issue in staging/local first, test the fix, then deploy carefully to minimize downtime and risk to your live system.
Do you work with AI-generated code (Cursor, Lovable, Replit, Bolt)?
Yes. I regularly fix and stabilize backends built with Cursor, Lovable, Replit, and Bolt. I can read AI-generated code quickly, spot the root cause, and clean it up without breaking what already works.
