I will fix your react nextjs and supabase bugs build errors and deployment issues
John
Sobre este Serviço
YOUR APP IS BROKEN AND YOU NEED IT WORKING.
I fix one clearly defined problem in React, Next.js, TypeScript or Supabase apps. You get the fix, testing, and a written explanation of the cause.
WHAT I FIX MOST OFTEN
· Next.js build failures and Vercel deploy errors
· Hydration and "works locally, breaks in production"
· Supabase auth: login, redirects, sessions, RLS
· API and integration issues
· Broken mobile layouts
· Forms that won't submit
· Small React and TypeScript bugs
HOW IT WORKS
1. You send the repo or URL and how to reproduce it
2. I confirm I can reproduce it before you pay beyond the gig
3. I fix it, test it, and write up what was wrong
4. One revision on the original issue is included
WHO I AM
I've shipped two live products on this stack: baandesk.com (AI receptionist, LINE bot, three languages) and prep-less.com (SaaS for ESL tutors). I use Claude Code to diagnose fast and stay responsible for what ships.
WHAT I DON'T DO
No security audits, no crypto or payment work, no whole-app rebuilds. If your problem can't be clearly scoped, I'll say so instead of taking your money.
Message me with the error and I'll tell you honestly if I can fix it.

Idiomas
Inglês
I fix broken React, Next.js and Supabase apps.
Usually it's one specific thing. A build that dies on Vercel but runs fine locally. A Supabase login that dumps the user on a blank page. A form that swallows submissions without a word.
I've shipped two products on this stack. Baan Desk answers guesthouse messages on LINE in three languages. Prep-less writes lesson plans for ESL tutors. Both are live, go and look.
Send me the error and how you reproduce it. I'll tell you straight whether I can fix it before you order anything.
Perguntas frequentes
Do you use AI to write the code?
I use Claude Code and AI-assisted tooling to work quickly. I read, test and take responsibility for everything that ships. You're hiring me, not a bot.
What if you can't fix it?
I'll tell you before you pay. If I can't reproduce it or it's outside what I do, I say so.
Can you rebuild my whole app?
No. I do small, clearly defined work. That's the whole point of the fixed prices.
What if the fix reveals more problems?
I'll show you what I found and quote it separately. I won't quietly expand the scope.
Do you work with WordPress or PHP?
No. React, Next.js, TypeScript, Supabase, Node and Python only.
