I will fix react, node js or mongodb bugs in your web app fast
Saad Bin Khalid
About this gig
Your React app has a bug that's blocking everything. Your Node.js API keeps throwing errors you can't trace. Your MongoDB query returns wrong data. I fix it fast.
I work in React and Node.js daily on real production codebases. I've fixed broken JWT auth flows, CORS errors that block entire APIs, React state bugs causing ghost re-renders, slow MongoDB aggregations killing load time, and Socket.IO connection drops in live systems. I don't just patch symptoms I find the root cause and fix it right.
BUGS I FIX
- React bugs useState, useEffect, hooks, context, React Router
- Node.js / Express API errors, CORS, middleware, auth issues
- MongoDB wrong query results, slow aggregations, schema bugs
- Responsive of website
- API integration errors
- TypeScript type errors and compilation failures
- Next.js App Router, SSR, getServerSideProps, hydration errors
HOW I WORK
- You describe the bug and share your code (GitHub or ZIP)
- I diagnose it and confirm scope before you order
- I fix it, test it, and deliver with a written explanation
- You understand what broke not just that it's fixed
BEFORE ORDERING
Message me first describe the bug and I'll confirm it's fixable within the package you have in mind. No

I'm a full-stack developer specializing in React, Node.js, and MongoDB — and I work on production systems, not tutorial projects.
I've shipped a real-time CRM (power dialer, RBAC, Socket.IO) used by a live sales team, a luxury e-commerce store with Framer Motion animations, and a Next.js agency site with a custom design system.
I build landing pages, admin dashboards, SaaS MVPs, and role-based systems — from Figma or from scratch.
Currently enrolled in BS, Computer Science at NED University of Engineering & Technology.

FAQ
How do I share my code with you?
GitHub link, ZIP file, or pasting the relevant snippet in the chat — I'll work with whatever you're comfortable sharing. For complex bugs, a GitHub repo with the relevant file open at the problem area is fastest.
What if you can't fix the bug?
I always diagnose before you order. If it's out of scope or genuinely unfixable within the package, I'll tell you before you commit — not after. I don't take orders I can't deliver on.
Will you explain what caused the bug?
Always. Every fix comes with a short written explanation of what the root cause was and what I changed — so you understand it, not just that it's fixed.
