Full Proven Proposal Cover Letter
Hi Nathan,
Saw your posting regarding data segregation and security concerns with your Supabase Postgres schema. I have secured dozens of production multi-tenant applications using battle-tested Row Level Security (RLS) patterns.
Here is how I will secure your database:
1. Embed `tenant_id` claims into Supabase auth JWTs and enforce RLS policies across all SELECT, INSERT, UPDATE, and DELETE operations.
2. Add composite indexes on `(tenant_id, id)` to prevent RLS policy evaluation from slowing down heavy table queries.
3. Write automated pgTAP security unit tests verifying that user A can never read or mutate user B's records.
I can run an automated RLS audit script on your schema today. Shall we discuss further?
Best,
