Full-stack developer

We are looking for a full-stack developer to build a web application from a completed technical specification. The architecture, database schema, security policies, and backend logic are fully documented. Your job is to implement, wire together, and deploy a production-ready MVP.
This is a fixed-scope project with clear deliverables. The ideal candidate is experienced with Supabase, React/TypeScript, and Stripe — and is comfortable working independently from a technical brief.

What Is Already Done
The following have been fully designed and are provided to you on day one:
• PostgreSQL schema (10 tables, indexes, triggers, enum types)
• Row Level Security (RLS) policies for every table
• Multi-level referral payout engine (SQL functions + views)
• Stripe webhook handler (TypeScript, ready to deploy as Supabase Edge Function)
• Interactive UI prototype (HTML/React mockup of all screens)
• Architecture diagram and implementation README

Deliverables
1. Backend Setup
• Deploy all SQL files to Supabase project in correct order
• Configure Supabase Auth (email/password + magic link)
• Set up Supabase Storage bucket for project file attachments
• Enable Realtime on messages, notifications, invites, and bids tables
• Deploy Stripe webhook as Supabase Edge Function
• Configure Stripe product ($10/month), Connect for payouts, and webhook events
• Set up Resend for transactional email (invite notifications, payment alerts)
• Enable pg_cron and schedule monthly payout batch job
2. Frontend (React + TypeScript + Vite)
• Onboarding flow: signup, role/specialty selection, referral code capture
• Professional card page: editable profile, share link, QR code, view analytics
• Project dashboard: post project, set visibility, upload attachments
• Invite system: invite by email ---------- real-time status tracking
• Bid management: submit bid, review bids, update bid status
• Discover page: searchable/filterable professional directory
• Messaging: real-time direct messages and project-threaded messages
• Earnings dashboard: referral tree, per-level earnings, payout history
• Billing page: Stripe Customer Portal embed for subscription management
• Notifications: in-app bell + unread count, mark-as-read
3. Public Pages (no auth required)
• Share card page: ---------- /card/ — public professional profile
• Referral landing: ---------- /join?ref= — captures referral before signup
• Marketing landing page (provided as HTML, convert to React)
4. Quality & Delivery
• Responsive design (desktop + tablet priority, mobile-friendly)
• Deployed to Vercel (frontend) and Supabase (backend)
• Environment variables documented
• Brief handover call / Loom walkthrough on delivery
