Full-Stack Dev (React Native + Next.js + Supabase) — Take Over Live Health App

We're an early-stage women's health platform, pre-launch and working toward our first paying members. The product is built and partly live, and we need an engineer who can own it. You'd be taking over an existing codebase: a React Native iOS app, a Next.js member portal, and a Supabase backend. Not a rebuild. The job is to stabilise what's there while continuing to ship toward launch. What you'd own React Native iOS app, through App Store release Next.js member portal Supabase backend: Postgres, RLS, edge functions, environment management Integrations: Stripe subscriptions, lab ordering, forms, messaging, analytics Required Strong Postgres (schema, migrations, RLS policies). Supabase as a Postgres platform, not a client-side BaaS Supabase Edge Functions in production (Deno/TypeScript), secrets, environment branching Stripe subscriptions: webhooks, invoices, coupons Webhook and integration engineering: signature verification, idempotency, retries, replay React Native iOS shipped to the App Store Next.js, React, TypeScript, Tailwind, shadcn/ui Experience in a regulated domain (health, fintech, insurance). HIPAA familiarity is a plus, not a blocker Error tracking and monitoring in production How we work You get user stories and acceptance criteria, not implementation instructions. Architecture calls are yours. You'd be the only engineer on the platform for a while, working async with our product lead in Ireland. Overlap of at least 4 hours with GMT. To apply, tell us A codebase you inherited: what state it was in, and the first three things you changed A production bug you diagnosed in a webhook or integration path An app you shipped to the App Store (link if public) Please skip the template cover letter. Answer the three questions and we'll read it. Engagement Ongoing, long-term, full-time or close to it. We'll start with a small paid piece of real work before either side commits.
