Your AI-built app worked in the preview, but now it breaks: build errors, blank pages, login that doesn't work, database errors, or it won't deploy. I'll find the real cause and fix it — not just patch the symptom.
What I fix:
- Build and deploy errors (Vercel, Netlify, Cloudflare, your own server)
- Authentication and sessions (Supabase Auth, Clerk, NextAuth)
- Database issues: Supabase / Postgres queries, row-level security, migrations
- Payments and webhooks that don't fire
- Broken pages, API routes, environment variables, CORS
- Slow or messy code that keeps breaking after every AI prompt
How it works:
- You send the repo (GitHub invite or zip) and describe what's broken.
- I reproduce the problem and tell you what's causing it before changing anything.
- I fix it, test it on a live URL and send a short note: what was wrong, what I changed, how to avoid it next time.
Tech: React, Next.js, TypeScript, Node.js, Supabase, Postgres, Prisma, Tailwind.
Not sure it's a fit? Message me with a screenshot of the error before ordering — I'll tell you honestly whether I can fix it.
