Misbah Nazir
About this gig
Having a bug in your MERN application that you just can't figure out?
I can help you find and fix bugs in your React, Node.js, JavaScript, or MERN stack application.
Whether it's a frontend issue, API error, authentication problem, unexpected behavior, or a database-related bug, I'll first understand the issue and then work on the actual cause instead of applying a quick temporary fix.
What I can help with:
- React and frontend bugs
- Node.js / Express API errors
- MongoDB-related issues
- Authentication and JWT problems
- API integration issues
- Form and functionality errors
- UI and responsive issues
- JavaScript errors
- Performance-related issues
How I work:
1. Understand You show me the issue and explain what is happening.
2. Diagnose I trace the problem and identify its cause.
3. Fix I make the necessary changes to your code.
4. Test I test the affected functionality to make sure the fix works as expected.
I don't believe in changing random lines of code just to make an error disappear. The goal is to understand what's causing the problem and fix it properly.
If you're not sure whether your issue is covered, send me a message before placing an order.
Let's get your application work properly
