About this gig

Stuck on a bug you can't figure out? Code working but you're not confident it's clean or secure?


I'm a MERN Stack Developer with 2+ years of production experience. I've debugged React frontends, Express APIs, MongoDB queries, and Next.js applications for real clients.


WHAT I FIX:

React and Next.js bugs (UI, state, rendering issues)

Node.js and Express backend errors

REST API issues (wrong responses, auth errors, CORS)

MongoDB and PostgreSQL query problems

Performance issues and slow load times

JavaScript and TypeScript errors


WHAT I REVIEW:

Code quality and structure

Security vulnerabilities

Database query efficiency

API design and error handling

Component architecture


HOW IT WORKS:

1. Share your code and describe the problem

2. I identify the root cause not just the symptom

3. I deliver fixed code with clear explanation of what was wrong and why


I don't just patch I explain so you understand the fix and it doesn't happen again.
