Supabase Integration for Multivendor Platform

I’m close to launching a fairly sophisticated multivendor application and now want Supabase wired in so the build is truly production-ready.

Here’s what I need:

• User authentication – email / password, social log-ins, secure session management and token refresh, all tied into my existing front-end components.
• A fresh database schema designed in Supabase from the ground up. No legacy tables to migrate, so we can create tables, relationships, RLS policies and indexes with best-practice naming and performance in mind.
• Real-time subscriptions so vendors, buyers and admins see updates instantly (orders, inventory, messaging, etc.).

You’ll set up the Supabase project, configure security (Row Level Security, policies, environment variables), and expose well-documented endpoints or Supabase client calls that my front-end can consume. I’ll also need concise deployment instructions plus a quick hand-off call or video walkthrough so I can maintain things afterwards.

If you’ve already taken apps to production on Supabase and you’re comfortable balancing performance, security and scalability, I’d love to see how you’d approach this.
