I will fix the supabase database and auth in your ai generated app
Gabriel M
About this gig
Your app works until it doesn't. A new feature breaks an old one, users see data that isn't theirs, queries crawl, or Supabase throws policy errors nobody can explain.
This is normal. AI builders generate the interface well and the data layer badly. The schema was guessed at, row-level security was either skipped or copy-pasted wrong, and nothing has an index.
What I fix
- Row-level security policies that leak data between users or block legitimate access
- Auth flows, sessions, roles and permissions
- Schema and relationship problems, including migrations that won't run
- Slow queries and missing indexes
- Broken edge functions, triggers and storage rules
- API routes returning wrong or inconsistent data
How it works
Start with the Audit package. I go through your database and auth setup and send you a written report: what's broken, what's a security risk, what it costs to fix. It's yours whether or not you hire me for the fix.
If you already know what's wrong, order Standard or Premium directly and describe it.
What I need from you: repo access or a Supabase invite, and a sentence on what's going wrong.
Message me before ordering if you're unsure which package fits. I'll tell you honestly.

I build and fix the backend of apps that AI tools got halfway.
Lovable, Base44, Bolt and Cursor write decent interfaces and poor data layers: broken RLS policies, missing indexes, auth that leaks data between users, and schemas that can't support the next feature you want to add. That's the part I fix.
I work in Supabase, Postgres, Node and Python. Small, clearly scoped jobs, a written plan before I start, and a walkthrough at the end so you understand what changed.
I'm early in my freelance career, which is why my prices are what they are. The work isn't.
FAQ
hich AI builders do you work with?
Lovable, Base44, Bolt, Replit, v0, Cursor, and anything else that outputs a normal repo with Supabase or Postgres behind it
Can you fix the frontend too?
I focus on the backend. If the issue turns out to be in the UI I'll tell you in the audit and we can start debating what to do from there.
Is my code safe?
I only need access for the duration of the job and I'll ask you to revoke it when we're done. Happy to sign an NDA.
What if you can't fix it?
If the audit shows the problem is outside what I do, I say so and you keep the report.
