I will fix bugs and issues in your nodejs, express, or mongodb app
Jmydev
Sobre este Serviço
Is your Node.js, Express, or MongoDB app throwing errors, crashing, or just not behaving the way it should? I'll find the root cause and fix it not just patch the symptom.
I'm a backend developer specializing in Node.js/Express/MongoDB, with experience on production systems including VBooking, one of the Middle East's larger AI travel platforms where I worked on a 4-year-old codebase handling live bookings, transactions, and supplier integrations. I know how to work inside existing code without breaking what already works.
What I can fix:
- API errors and unexpected crashes
- Database query issues / MongoDB connection problems
- Authentication & middleware bugs
- Broken integrations (Stripe, third-party APIs, etc.)
- Performance bottlenecks and slow endpoints
- Logic errors causing wrong data or behavior
Send me the error, the repo, or just a description of what's going wrong I'll diagnose it clearly before touching any code, so you know exactly what's happening and how it'll be fixed.

Idiomas
Árabe, Inglês
I build fast, secure backends and web apps that businesses actually run on REST APIs, booking systems, payment integrations, and full-stack builds with Node.js, Express, and React.
I lead a small team, so whether you need a single API or a complete website, you get clean, production-ready work from one reliable point of contact. I've built backends for live products, including VBooking, one of the biggest travel hubs in the Middle East.
Tell me what you're building
I'll help you ship it.

Perguntas frequentes
Do I need to share my full codebase?
Only the relevant part. I'll tell you exactly what I need after you describe the issue.
What if the bug takes longer than expected to find?
I'll always communicate before exceeding scope; no surprise charges.
Can you work with my existing hosting/deployment setup?
Yes, I work within your current environment unless we agree otherwise.
Do you fix front-end bugs too?
My focus is backend but I can flag front-end issues but won't fix them unless agreed separately.
What if it's not actually a bug but missing functionality?
I'll let you know and we can scope it as a small feature add instead.
