About this gig

Is your React, Node.js, or MERN stack website broken? I'll fix it fast!


Hi! I'm a full stack developer specializing in debugging and fixing errors in modern JavaScript web apps. Whether it's a frustrating console error, a broken API, a database issue, or UI that won't behave I'll get your site working smoothly.


I fix bugs in:

  • React & Next.js (frontend errors, hooks, rendering issues)
  • Node.js & Express (server, API, backend logic)
  • MongoDB & PostgreSQL (database queries & connections)
  • JavaScript & TypeScript errors
  • Responsive/CSS layout bugs


Why choose me:

  • Fast delivery (as quick as 1 day)
  • Proper bug investigation I find the root cause, not just patch it
  • Clean code with clear communication
  • Revisions until you're satisfied


I treat every project with care and deliver working, tested code. Have a complex issue? Message me before ordering and I'll let you know exactly how I can help.
