Full Stack Engineer

CI/CD , React Native , RevenueCat , Supabase , TypeScript What our client is building Our client is building a repeatable process to ship high-quality, tightly-scoped consumer iOS apps and prosumer web apps using AI — from demand testing ideas to building the backend and frontend, UX/UI design, and GTM/growth execution. They iterate and strengthen that process by launching 4–5 ideas per month. Their core thesis is that AI can repeatedly ship high-growth, lightweight products with a small team and strong execution standards. Speed, product taste, and iteration quality are critical. They are currently bootstrapping ventures for strong cash flow while remaining open to venture funding if a product reaches significant traction. What you’d work on You would help build the backend infrastructure and internal platform layer that every new venture inherits — reducing the need to rebuild common systems like authentication, AI integrations, payments, observability, and edge services from scratch. This role also includes shipping individual ventures end-to-end when needed. Examples of projects include: Shared AI prompt routing with provider abstraction, cost tracking, and evaluation frameworks Venture scaffolding systems where a single command provisions a new app backend with migrations, authentication, and payment integrations Launch-readiness automation and CI gates validating analytics, paywalls, push notifications, deep links, and error reporting before launch Per-venture observability dashboards tracking activation, conversion, AI cost per user, stability metrics, and launch performance Backend architecture and APIs for new ventures as they are launched The objective is not simply building one application — it is building the infrastructure factory that accelerates every future launch.
