Next.js + Supabase + Sanity + Vercel — 3-Hour Infra Setup ($60 Fixed)

Small, tightly scoped one-off job. Everything is already decided, so this is execution, not discovery. Set up in 3 hours: - Next.js App Router (TypeScript), ESLint + Prettier - Supabase connected: auth, base schema, RLS policies - Sanity Studio embedded with initial schema - Vercel deployed, env vars set for prod and preview - CLAUDE.md at repo root so Claude Code can work in it Must have shipped production work on this exact stack. In your proposal, answer one question: how do you write Supabase RLS policies when the app needs both authenticated users and public read access? No answer, no review. Fixed $60, paid on delivery. Start within 48 hours.
