I will fix broken supabase auth, rls errors, and secure your database
Nabeel Shahid
About this gig
Did you know 1 in 10 AI-generated apps ships with an exposed database anyone with your app's public key can read or edit ALL your users' data?
This happens because (Lovable, Bolt, Base44, v0) often generate Supabase backends with Row Level Security (RLS) missing or misconfigured. Your app looks finished, but the data behind it is wide open.
I audit and fix your Supabase security: proper RLS policies on every table, correct authentication flow, and verification that your app is actually locked down not just working.
What I check and fix:
- RLS enabled and correctly scoped on every table
- Auth flow issues (signup, login, session handling)
- Exposed service_role keys or anon key misuse
- Permission-denied errors caused by broken policies
- Multi-user data isolation (users seeing each other's data)
Message me your platform (Lovable, Bolt, Base44, or custom) and what's going wrong, and I'll tell you honestly what needs fixing.

FAQ
My users can see each other's data — can you fix this?
Yes, this is the #1 RLS problem. I'll set up proper policies so users only see their own data.
Do I need to give you access to my Supabase project?
Yes, I'll need your project URL and anon key. For fixes, I may need temporary service_role access. I never share or store your credentials.
Will fixing RLS break my existing app?
I test everything before delivery. If something breaks, I'll fix it free. I can also set up a staging environment first.
Can you set up admin/manager/user roles?
Yes. I create role-based access using helper functions and JWT claims — admins see everything, users see only their data.
My auth works on localhost but not on Vercel/Netlify — why?
Usually it's a redirect URL or environment variable issue. I can diagnose and fix this quickly.
How do I know if my database is currently insecure?
Send me your project details and I'll do a free 5-minute security check. If RLS is off on any user data table, it's insecure.
Can you fix slow queries caused by RLS?
Yes. Missing indexes on policy columns are the #1 cause of slow RLS queries. I'll add proper indexes and optimize your policies.
Do you work with apps built in Lovable, Bolt, or Base44?
Absolutely. Most of my clients come from AI builders that ship insecure Supabase setups. I specialize in fixing them.
What if I have 20+ tables?
Message me first. I'll give you a custom quote based on table count and complexity.
Do you provide documentation after setup?
Yes. Premium package includes full documentation of all policies, roles, and security recommendations.
