Backend Developer — Supabase + Stripe + Edge Functions

The short version I'm the founder of BAM, a basketball tech company. I own all the frontend (React + Vite). I need a backend specialist to complete the infrastructure for two interconnected platforms and a coaching tools suite. Specs are thorough, handoff doc is ready, and I need someone who can start immediately and move fast. What you're building Two platforms on a shared Supabase instance: BAM Coaches — coach certification platform ($39.99/mo Stripe subscription). Schema is 23 tables and already documented. Needs validation, Stripe wiring, API key migration to serverless, content seeding, and a full QA pass. BAM Virtual Academy — player development platform (programs, habit tracking, leaderboards, VA+ coaching tier). Full backend build from a detailed spec — 10 tables, Stripe checkout + webhooks, points system, Supabase Realtime. Coaching Tools Suite — three add-on tools (Advantage Flow System, Adaptive Shooting Framework, PDP Builder). Priority fixes: session data persistence, unified auth hub, Anthropic API Edge Function, Stripe tier gating. Stack Supabase (PostgreSQL + Auth + RLS + Edge Functions + Realtime) · Stripe (Checkout, Webhooks, Customer Portal) · Mux · Vercel · React/Vite (frontend only — not your concern) You're a fit if You've shipped Supabase RLS on a multi-role app — not just basic auth, actual row-level security with multiple user types reading each other's data You've built Stripe webhook handlers end-to-end — checkout, subscription lifecycle, failed payments, cancellations You use AI tooling (Cursor, Claude, etc.) in your workflow and it shows in your speed You can start immediately What's provided Full handoff document, canonical schema file (683 lines), complete VA backend spec, ASF context doc, and a scoped task list with priorities. You won't be guessing at requirements. Budget Open — make your case based on your rate and approach. Devs who use AI tooling effectively tend to be faster and I price accordingly. This project also comes with a retainer opportunity. If the initial build goes well, I want someone on call for ongoing maintenance and feature work as both platforms grow. To apply Tell me about a project where you shipped Supabase RLS and Stripe webhooks together. That's the bar. Everything else we can figure out.
