Senior Full-Stack Developer - Supabase & PostgreSQL Security Expert for Pre-Launch Review

I'm a non-technical founder and I need a senior full-stack developer and Supabase/PostgreSQL expert to run a read-only pre-launch code and security review on a feature-complete consumer app launching soon on the App Store and Google Play. Stack is React/TypeScript/Vite, Capacitor, Supabase, Twilio Verify, and Vercel. You need real production experience with Supabase RLS policies and PostgreSQL, plus a track record shipping Capacitor apps to both app stores. Review covers the facility database pipeline that handles hospital records, addresses, and map coordinates. Deliverable is a plain-language report, prioritized by severity, written for a non-technical founder. A reviewer orientation guide is in the repo.
