About this gig

Stuck with a frustrating bug in your React, Next.js, or MERN stack app? I'll find the root cause and fix it cleanly, properly, and with testing.

I specialize in fixing React.js, Next.js, Node.js, Express.js, and MongoDB bugs and errors. Whether you're facing a broken feature, API error, console error, authentication issue, database problem, unexpected crash, or deployment issue, I'll diagnose the problem and fix it properly, not just apply a temporary patch.

What I can fix:

  • React & Next.js bugs
  • Node.js & Express.js errors
  • API & backend issues
  • MongoDB & database problems
  • Authentication & JWT issues
  • UI & JavaScript errors
  • Build & deployment errors
  • Broken features & unexpected crashes

What you get:

  • Proper bug investigation
  • Clean & tested fixes
  • Root-cause debugging
  • Clear communication
  • Fast turnaround

Need multiple bugs fixed? Choose the package that fits your needs or add Additional Bug Fixes.

I have hands-on experience building MERN and Next.js applications, SaaS dashboards, and POS and inventory systems, so I can understand your codebase quickly and troubleshoot efficiently.

Have an error right now? Send me the details, screenshot, or GitHub code, and let's get it fixed.
