I will fix bugs in your lovable, bolt or replit app and secure supabase auth

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.
