Security Review for TaskDrop

I’ve built TaskDrop, a local and remote task marketplace, and need an experienced security engineer to review it and help make it production-ready. The app includes React Native / Expo for Android and web, Supabase with Postgres, Row Level Security, Edge Functions, and Auth, plus a Vercel admin panel, Inngest, Firebase, Sentry, and ImageKit. I need a security review covering database and API access, authentication flows, admin panel permissions, secret management, and hands-on testing in staging. Deliverables include a report with findings ranked by severity and clear fix steps, plus a go-live checklist for launch.
