About this gig
Is your React or Node.js application showing errors, broken features, API problems, or unexpected behavior?
I will diagnose the root cause and fix bugs in your MERN stack application.
What I can fix:
React.js errors and broken components
Node.js and Express.js API issues
MongoDB queries and database problems
JWT authentication and authorization issues
REST API and frontend-backend connection problems
CORS and environment configuration issues
Routing and state management bugs
Form and validation errors
npm, build, and dependency issues
Deployment and production errors
My process:
- Understand and reproduce the issue
- Identify the root cause
- Implement a clean fix
- Test the affected functionality
- Explain what was fixed
I don't just hide error messages or apply temporary workarounds. My goal is to identify the actual cause and deliver a reliable fix.
Technologies:
React.js Node.js Express.js MongoDB JavaScript REST API JWT
Please message me before ordering if the issue is complex or you are unsure which package you need.
Send me the error, screenshot/video, or a short explanation of the problem, and I'll help you determine the right scope.
