I will fix and stabilize your vibe coded nextjs and supabase app
Alvaro
About this gig
Did you build an app with Lovable, Cursor, Bolt or Replit, and now it's buggy, insecure, or breaking as it grows? That's exactly what I fix.
I'm a full-stack developer who ships production Next.js + Supabase apps for real businesses (ERP, healthcare, multi-tenant platforms). I take AI-generated "vibe-coded" apps and turn them into clean, secure, production-ready software, without throwing away your work.
What I'll do: fix bugs and broken flows; lock down security and auth (Supabase RLS / row-level security done right); clean up messy AI-generated code so it's maintainable; optimize performance and database queries; and get it deployed and running reliably on Vercel.
How it works: you share your repo (or Lovable/Replit project) and what's broken; I audit it and tell you exactly what's wrong and what it will take; then I fix it, redeploy, and hand it back working, with notes.
Stack: Next.js, React, TypeScript, Supabase, PostgreSQL, Vercel.
Not sure which package fits? Message me with your app first and I'll tell you honestly before you order.

FAQ
I built my app on Lovable or Replit, can you still help?
Yes. Those tools export standard Next.js / React + Supabase, which is exactly my stack. I work from your repo or exported project.
Will you rebuild my app from scratch?
No. I keep your work and fix or harden what's already there. If a rebuild is genuinely cheaper or safer, I'll tell you honestly first.
