I will fix supabase rls policy, auth login errors and vibe coded app bugs
FELIX
Over deze dienst
Stuck on new row violates row level security policy? Signup throwing a 500 error? Data sitting right there in your table but your app shows a blank screen? Your Supabase RLS and auth config is broken. Your idea is fine.
I fix the backend that Lovable, Bolt.new, v0, Replit, Base44 and CatDoes leave half finished.
WHAT I FIX
RLS policies written properly per table: select, insert, update, delete
Signup and login failures, email confirmation, password reset, expired JWT and session bugs
Profiles row not being created on signup (missing trigger or function)
Foreign keys, schema relationships and broken migrations
Storage bucket permissions and upload denied errors
Google, Apple and magic link social login setup
WHY ME
24 hour delivery. Most auth bugs are diagnosed inside an hour
Loom video showing your bug reproduced, then fixed, then tested
Plain English explanation so your AI builder does not undo it next prompt
I work in a branch. Your live user data is never touched
Send me your error message or project link and I will tell you exactly what is wrong before you order. Diagnosis is free.

I fix apps that AI built and then abandoned.
Lovable, Bolt.new, v0, Replit, CatDoes and Cursor are brilliant at generating screens and genuinely terrible at everything behind them. Supabase RLS, Expo builds, Stripe webhooks, App Store review. That is the part where founders get stuck for three days and I get unstuck in one.
React Native, Expo, TypeScript, Supabase, Postgres, Stripe, RevenueCat, Vercel.
Send me the error message, not an apology for it. I have seen worse. I will tell you what is wrong before you pay me anything.
Veelgestelde vragen
How fast can you start?
Send the error message now. I reply within the hour and most Basic orders are delivered the same day.
Will this break my existing users or data?
No. I write incremental, backward-compatible SQL migrations and test on a branch before anything touches production. Your existing users and rows stay exactly as they are.
Do I have to give you my password?
Never. Invite me to your Supabase project as a member and send a read-only GitHub invite. I will never ask for a password, and you revoke my access the moment we finish.
Do you work with Lovable, Bolt.new, v0, Replit, Base44 and CatDoes apps?
Yes, all of them, plus Cursor and Emergent. Different builders, same three mistakes every time.
What is a Supabase RLS error and why did my AI builder cause it?
Row Level Security is switched on by default, so your tables are locked. The AI generates a gorgeous login screen and forgets the SQL policy that grants access. The result is an app that looks perfect and works for nobody.
