I will fix node js bugs API errors and database performance
Nabil Elhady
Über diesen Service
There's always a specific reason an API is slow, a background job keeps crashing, or a database is melting under load. I find it and fix it properlynot with a temporary patch that breaks something else in three weeks.
I specialize in:
- Node.js / Next.js / Express bug fixes
- Slow database queries (PostgreSQL, MySQL, MongoDB)
- Crashing background jobs (BullMQ, Redis queues)
- API errors, 401s, CORS issues, broken auth flows
- Memory leaks and server timeouts
Real example: A production database query taking 800msdiagnosed, restructured, and dropped to 120ms. Same hardware. No infrastructure changes.
Send me your error logs, your repo link, or just describe what's broken. I will tell you within a few hours if I can fix it and exactly how long it will take.

FAQ
Do I need to message you before placing an order?
Yes, please send me a quick message first! I need to review your error logs or repository to confirm the exact issue and make sure I can fix it within the timeframe.
What if the bug requires a complete rewrite of my API?
If the issue requires a massive architectural overhaul rather than a standard bug fix, I will inform you immediately during our initial chat and provide a custom quote for the refactoring.
What databases do you work with for query optimization?
I specialize in PostgreSQL, MySQL, and MongoDB. I can help with indexing, complex relational queries, and raw SQL optimization.
What do you need from me to start?
Depending on the issue, I will usually need access to your source code (via a GitHub/GitLab invite), relevant error logs, and occasionally staging database access.
