I will fix react nodejs express and mongodb bugs fast with root cause analysis
Sandeep
About this gig
Is your MERN stack application throwing errors you can't solve? I specialize in diagnosing and fixing bugs across the full React, Node.js, Express, and MongoDB stack fast, cleanly, and without breaking your existing features.
What I fix:
- React component errors, state management bugs, hook issues
- Node.js and Express API failures, route errors, middleware problems
- MongoDB connection issues, query errors, schema validation problems
- JWT authentication bugs and session handling errors
- CORS errors, deployment issues, environment configuration problems
What you get:
- Root cause explanation (not just a fix you'll understand what went wrong)
- Clean, commented code
- Test confirmation that the fix works
- No damage to existing features
I have built full-stack applications using React, Spring Boot, PostgreSQL, and JWT authentication. I understand how these systems connect and where they break.
Send me your error message or GitHub link and I'll review it before you order no obligation.
