About this gig

Is your React or Next.js application throwing errors, failing to build, or behaving unexpectedly? I can help investigate the issue, identify the root cause, and fix it cleanly without unnecessary changes to your codebase.


I work with modern React/Next.js applications using TypeScript, Tailwind CSS, REST APIs, PostgreSQL, Prisma, Supabase, and Vercel.


I can help with:

  • React and Next.js bugs
  • TypeScript errors
  • Component and state issues
  • Routing and navigation problems
  • API integration errors
  • Build and compilation errors
  • Vercel deployment issues
  • Responsive UI and Tailwind CSS bugs
  • Authentication and protected-route issues
  • Frontend/backend connection problems
  • Performance-related issues


What you can expect


I will first investigate the problem, find the actual cause, and implement a clean fix while keeping your existing project structure intact.


For larger or complicated issues, I can also provide a short explanation of the root cause and the changes made.


Before ordering

Please send me:

  • A short description of the problem
  • Error messages or screenshots
  • Steps to reproduce the issue
  • Your repository/source code
