About this gig

Your Lovable, Bolt or Replit app worked in preview. Now login breaks, data disappears, or the AI keeps "fixing" one bug and creating two more.


I'm a full-stack engineer (React, Next.js, Node, Supabase). I read the actual code, find the root cause and fix it properly, without burning your credits.


WHAT I FIX

- Blank screens, build errors and failed deploys

- Broken sign-up, login and password reset

- Supabase errors, missing data and slow queries

- Stripe, Lemon Squeezy and webhook problems

- Features the AI half-built and left broken


SECURITY CHECK (most AI apps fail this)

- Supabase Row Level Security, so users can't read each other's data

- Secret API keys removed from the browser code

- Protected admin pages and routes


I've taken a Lovable-built app to production myself: Supabase with RLS, verified payment webhooks, signed file URLs and a live custom domain.


HOW TO START

Send me your app link or GitHub repo and a short description or screenshot of the problem. I'll reply with what's wrong and which package fits, usually within an hour.
