I need two specific, high-priority modules built and integrated into my existing Supabase architecture: 1. Automated Payment & Vendor Splits (Stripe Connect) Implement Stripe Connect (Express or Standard) to handle multi-sided transactions. Automate a 40/60 profit split (40% Platform / 60% Creator) at the point of sale. Configure automated onboarding flows for student "vendors" (KYC/KYB). 2. Dynamic DRM & Asset Security (The "Vault" Security) Implement Dynamic PDF Watermarking: Every file must be stamped with the Buyer’s Name, Email, and IP Address at the moment of download. Access Control: Ensure files are never directly accessible via a public URL; use Supabase Row Level Security (RLS) and Signed URLs to protect assets. Session Locking: Prevent account sharing by limiting active sessions or flagging suspicious IP activity. Technical Requirements Primary Stack: Supabase (PostgreSQL), JavaScript/TypeScript. Expertise: Deep experience with Stripe Connect API. Specialty: Knowledge of PDF manipulation libraries (e.g., pdf-lib or Puppeteer) for server-side watermarking. Mindset: You are a "Builder." You prefer clean, secure code over complex "bloatware."
