FAQ
What do you need from me to start fixing the bugs?
To fix your MERN stack bugs, I need your project files via GitHub repo or ZIP file, a clear description of the issue, and steps to reproduce the bug. If your React or Node.js application is live, sharing the URL helps me diagnose the problem faster.
Can you fix both frontend and backend issues?
Yes! I handle the complete MERN stack — React.js frontend bugs, Node.js and Express backend errors, MongoDB database issues, and broken REST API endpoints. No matter where the bug is hiding, I will find and fix it.
Do you fix urgent or critical bugs?
Yes, most MERN stack bug fixes are delivered within 24 hours. For urgent React or Node.js issues that are breaking your live website, message me first and I will prioritize your project immediately.
What types of React bugs do you fix?
I fix React white screen errors, component not rendering, useState and useEffect hook issues, props drilling problems, API call failures, routing errors with React Router, and Redux state management bugs.
Can you fix Node.js and MongoDB errors?
Absolutely. I fix Node.js Express route errors, middleware issues, JWT authentication bugs, CORS errors, MongoDB connection failures, Mongoose schema problems, and slow or broken database queries.
Do you work on incomplete or messy MERN projects?
Yes, I specialize in fixing and completing existing MERN stack projects. Even if your codebase is unfinished or messy, I will clean it up, fix the bugs, and deliver working code
Do you offer code review or improvement suggestions?
Yes. Along with bug fixing, I review your full MERN stack code and suggest improvements for performance, security, and clean code structure — at no extra charge.
What if I am not satisfied with the fix?
Your satisfaction is my priority. I offer free revisions until your MERN stack application is fully working as expected. If the issue persists, we will work out a fair solution together.
