Backend Integration (Supabase + Stripe Connect) for Existing Single-Page Web App

Title: Backend Integration for Live Single-Page Creator App (Supabase + Stripe Connect) Description: I have a live, fully-designed Single Page Application (HTML/CSS/Vanilla JS) deployed on Netlify. The front-end UI, dark glassmorphism styling, client-side routing, and interactive modals are 100% complete. I need an experienced backend developer to connect real cloud infrastructure so the app is fully functional and revenue-ready. Deliverables: 1. Supabase PostgreSQL Integration: - Configure a lightweight schema for creators, posts, comments, and media. - Store media drops (images/video snippets) using Supabase Storage buckets. - Ensure all posts, ripples, and comments sync globally in real-time across devices. 2. Stripe Connect (80/20 Revenue Split): - Implement Stripe Connect Express onboarding so creators can link their payout accounts. - Configure Stripe Checkout sessions with platform application fees (80% transferred to the creator, 20% retained by platform). - Set up a webhook listener to verify payments and automatically unlock gated media for the paying user. Requirements: - Proven experience with Supabase (RLS, Storage, Realtime) and Stripe Connect. - Clean, minimal code that integrates directly into an existing Netlify-hosted setup (using Netlify serverless functions or lightweight backend). - Must be ready to start immediately. To apply, please begin your proposal with the word "WATERFALL" so I know you read the full brief. Share 1 or 2 past projects where you integrated Stripe Connect or Supabase.
