- REST API not returning correct responses
- TypeScript type and compilation errors
- Express middleware and routing issues
- Database query errors (MongoDB/PostgreSQL)
- npm package conflicts and dependency issues

- Memory leaks and performance issues
What you get:
- Root cause identified and fixed
- Clear written explanation of the bug
- Clean, tested code delivered
- Fix documentation (Standard & Premium)
- Detailed code comments (Premium only)
How it works:
1. Message me with your bug description
2. Share your code (GitHub, zip, or paste)
3. I fix it and explain what went wrong

I don't just patch symptoms I fix the actual root cause.

I'm a passionate Backend Developer focused on building scalable and efficient server-side applications using Node.js, TypeScript, and MongoDB/SQL. Recently graduated with a Bachelor's degree in Computer Engineering, I've gained hands-on experience through an internship and job where I built complete backend APIs for a game project and developed an NPM package offering multiple authentication methods.
FAQ
What information do I need to share with you?
Please share your code (via GitHub link, zip file, or direct paste), a description of the bug, what you expected to happen, and what is actually happening. Error logs and screenshots are very helpful too.
What if you can't fix my bug?
If I cannot fix your bug after reviewing the code, I will let you know before you place an order and give you a full refund if already ordered. I never take payment for work I cannot deliver.
Do you fix bugs in frontend JavaScript too?
Yes. I fix bugs in Node.js, Express, NestJS, plain JavaScript, TypeScript, and basic React/Next.js backend logic. For complex frontend UI bugs, please message me first to confirm.
How do you deliver the fixed code?
I deliver via GitHub (commit or PR), a zip file, or direct code paste — whichever you prefer. I always include a written explanation of what the bug was and exactly what I changed to fix it.
