Does your React or Next.js app have bugs? I'll fix them.


What I fix:

- Broken API calls and data fetching

- Styling and responsive issues

- Performance problems (slow rendering, unnecessary re-renders)

- Build and deployment errors


Stack: React, Next.js, TypeScript, JavaScript, Tailwind CSS, Supabase.


How we work:


1. You describe the bug and share your repo

2. I identify the root cause and confirm the fix

3. I fix it and show you what was wrong


Message me before ordering with a description of your bug.
