I will fix react, nodejs and mern stack bugs in your web app
Maaz Afzal
About this gig
Your React or Node app was working, and now it is not. A page throws an error, an API returns nothing, login stops working, or the layout breaks on mobile.
Send me the error before you order. I will look at it and tell you honestly if I can fix it, and what it will cost. If it is outside what I do, I will say so.
What I work with:
- React, JavaScript, Next.js
- Node.js, Express, MongoDB
- REST API and fetch or Axios errors
- JWT login and auth problems
- Tailwind and CSS layout issues
- Responsive and mobile bugs
- Vercel build and deploy errors
- Apps built with Lovable, Bolt, Replit and Cursor
What you get:
- The bug fixed and tested
- A clear explanation of what was wrong
- Clean code that matches your existing style
- No unrelated changes to your project
I do not work with WordPress, PHP, Shopify, Wix or React Native.
I have built production MERN apps including Cartify, a live store with JWT auth and an admin dashboard. I also completed an 8 week remote internship at Arch Technologies working as a developer.
Message me the error and a screenshot. I reply to every message.

MERN stack developer working with React, Node.js, Express and MongoDB.
Most of my work is debugging. A React app throws errors, an API stops returning data, a login breaks, a layout collapses on mobile. I find the real cause, fix it, and explain what was wrong in plain language.
I also work on apps built with AI tools like Lovable, Bolt and Replit. That code is React and Node underneath.
I built Cartify, a live MERN store with JWT auth and an admin dashboard, and did an 8 week remote internship at Arch Technologies.
Send me the error before ordering. If I cannot fix it, I will say so.

FAQ
Can you fix my bug? How do I know before ordering?
Message me first with the error and a screenshot or repo link. I will look and tell you honestly if I can fix it. If I cannot, I will say so instead of taking the order.
What do you need from me to start?
The error message or screenshot, a link to your code (GitHub, zip or a repo invite), and steps to reproduce the bug. If it is a live site, send the URL.
Do you work with WordPress, PHP or Shopify?
No. I work with React, Next.js, JavaScript, Node.js, Express and MongoDB only. If your project is WordPress, PHP, Shopify or Wix, I am not the right fit.
My app was built with Lovable, Bolt or Replit. Can you help?
Yes. Those tools generate React and Node code underneath, which is what I work with every day. Send me the project and the error you are seeing.
What if the bug is bigger than it looked?
I will tell you before starting any work. Sometimes a small bug points to a bigger problem. I will explain what I found and you decide whether to continue.
Will you change other parts of my code?
No. I fix what you asked for and leave the rest alone. If I notice something else worth fixing, I will mention it rather than change it myself.
Do you provide the source code?
Yes. You get the fixed code and a short note explaining what was wrong and what I changed.
Can you deploy the fix for me?
I can deploy to Vercel. For other hosting, I will send you the fixed code with instructions.
