You will get Supabase RLS Policy Fix & Database Security Setup.
Project details
Is your Supabase app throwing "permission denied" errors, blocking real user queries, or exposing data it shouldn't? I fix Row Level Security (RLS) issues fast secure and functional.
WHAT I FIX
• Blocked queries from missing or incorrect RLS policies
• Data leaks where users see records that aren't theirs
• Policies that work in the dashboard but fail in production
• Auth issues (Supabase Auth, custom JWT, service role misuse)
• Multi-tenant access control (users, teams)
• Slow queries from inefficient or overlapping policies
HOW IT WORKS
Share read only access or your schema + current policies. I audit your tables and auth setup, pinpoint the exact issue, fix and test it against your real queries, then deliver with a written summary of what changed.
WHY THIS MATTERS
RLS is the top source of bugs and security holes in Supabase apps especially ones built fast with AI tools like Lovable, Bolt, v0, or Cursor. One bad policy can lock out real users or expose your entire database.
MY STACK
Next.js, React, TypeScript, Supabase, PostgreSQL, Prisma, NestJS full-stack, so I'll flag deeper auth or API issues too.
Message me before ordering if you're unsure which package fits.

Steps for completing your project
After purchasing the project, send requirements so Salim can start the project.
Delivery time starts when Salim receives requirements from you.
Salim works on your project following the steps below.
Revisions may occur after the delivery date.
Audit your database
I review your schema, existing RLS policies, and auth setup to pinpoint exactly what's broken or missing
Diagnose the root cause
I identify whether the issue is a missing policy, a misconfigured condition, or a deeper auth/schema mismatch.
