Full-Stack Developer — SaaS MVP (Next.js + Supabase)

We are building a production-grade SaaS MVP and need a senior full-stack developer who has shipped real products — not just demos. The stack is Next.js 14 (App Router) on the front end and Supabase (Postgres + Auth + Storage) on the back end. You will own the full technical delivery from architecture decisions through to a deployed, scalable MVP. SCOPE OF WORK — Architect and implement a multi-tenant data model in Supabase using row-level security (RLS) — Build a responsive, high-performance frontend in Next.js 14 with server components and streaming — Integrate Supabase Auth (email/password, OAuth, magic link) with role-based access control — Design and expose a clean REST or tRPC API layer for frontend consumption — Stripe billing integration — subscriptions, webhooks, customer portal — Set up CI/CD pipelines (GitHub Actions), environment management, and Vercel deployments — Write unit and integration tests with a minimum 70% coverage threshold — Deliver clean, documented, handoff-ready code with a technical README WHAT WE'RE LOOKING FOR — Demonstrable experience shipping SaaS products end-to-end — portfolio links required — Deep expertise in Next.js (App Router), TypeScript, and Tailwind CSS — Strong Supabase/PostgreSQL knowledge: schema design, RLS policies, edge functions — Familiarity with Stripe, Resend or similar transactional email providers — Excellent async communication and the ability to work with minimal oversight — A bias for shipping: you prioritise working software over perfect abstractions HOW TO APPLY Please include in your proposal: (1) two or more live SaaS products you've shipped, (2) your preferred approach to multi-tenancy in Supabase, and (3) a rough timeline and milestone breakdown. Generic proposals will not be considered.
