About this gig

Is your React or Next.js application showing errors, bugs, or unexpected behavior? I can help you diagnose and fix it.

I am a full-stack developer experienced in building and maintaining production web applications using React, Next.js, Node.js, TypeScript, PostgreSQL, Prisma, Supabase, Redis, and Docker.

I can help with:

React and Next.js bugs

JavaScript and TypeScript errors

API and backend issues

Authentication problems

Supabase and PostgreSQL issues

Prisma/database errors

Responsive UI problems

Performance issues

Deployment and production errors

Integration problems

My approach: I first identify the root cause of the problem, explain what is causing it, implement the fix, and test the affected functionality to make sure the issue is properly resolved.

Please message me before ordering if your issue is complex or you are unsure which package you need.
