I will fix errors and repair broken react components
Mijanur Rahman
About this gig
Are bugs, errors, or unexpected issues stopping your React app from working smoothly?
You are in the place.
I help developers, businesses, and startups debug and repair React and Firebase applications. Whether something suddenly broke, an API stopped responding, or Firebase Auth is not working anymore, I can track down the issues and deliver a clean and stable fix.
My focus is always to identify the real cause of the problem, fix it properly, and make sure it does not come back.
What I can fix for you:
- React component crashes, or UI not rendering
- Broken state logic (Hooks, Context)
- Firebase authentication issues (login, signup, protected routes)
- Firestore read/write errors
- Slow performance or console warnings
- API request failures, incorrect data, or CORS errors
- Routing problems and navigation bugs
- Misconfigured Firebase setup or environment variables
- Build errors and deployment issues
Why clients choose me:
- Clean and maintainable code
- Quick communication and friendly support
- Focus on long-term stability
- 100% dedication until your issue is fixed
If you're not sure what's causing the error, send me a quick message. I'll take a look and suggest the best package for your issue.

FAQ
What do you need from me to get started?
Usually, I need access to your project files or GitHub repo, a description of the issue, and steps to reproduce the error. If the issue is related to Firebase, I may also need temporary access to your Firebase project settings.
Can you fix any type of React or Firebase bug?
Yes, I handle UI bugs, component issues, state problems, routing errors, Firebase auth issues, Firestore problems, API failures, and more. If the issue is unclear, send me a message and I’ll check it first.
What if I don’t know what’s causing the error?
No problem. You can send me screenshots, an error message, or a short description of what’s happening. I’ll investigate and explain the root cause before starting the fix.
Will my code be kept private and secure?
Absolutely. Your project stays 100% confidential. I never share code or project details with anyone.
Do you work on projects built with Node, Express, or APIs?
Yes. If your React app connects to a backend or custom API, I can debug and fix issues on both sides when needed.
What if the issue is bigger than the package I selected?
If the bug is more complex, I’ll inform you before starting. You can upgrade the package or we can create a custom offer that fits your needs.
Can you help set up Firebase from scratch?
Yes, I can help with full Firebase setup including authentication, Firestore, hosting, storage, and protected routing. This can be included in a custom offer.
Do you offer long-term support?
Yes. If you want ongoing maintenance or future updates, I can provide continued support through custom packages.
