Senior Full Stack Developer (TypeScript, React, React Native)

Wearton is a personal stylist app. It finds the user's colours from one selfie, keeps their clothes in a digital closet, and says what to wear for the weather and the events of the day. Hooky, our AI stylist, answers questions in a chat.

With virtual try-on, users see a piece of clothing on their own photo. Wearton runs on iPhone and Android, on the web, as a browser extension (Chrome, Edge, Firefox, Safari) and inside ChatGPT and Claude through an MCP server. All clients are one TypeScript codebase that shares code between them.

We are a small product startup. You will work directly with the founder and own features end to end: API, database, web app, browser extension and mobile app.

Build features across the whole stack: from an API route and a database migration on Cloudflare Workers to the React web app, the browser extension and the React Native app. Work with LLMs and image models (OpenRouter, Google Vertex AI): prompts, structured JSON output, daily limits and cost per request. Write automated tests with every change (Vitest, Jest, Testing Library, Maestro e2e).

Ship small changes often through GitHub Actions, and keep the API contract and docs up to date. Use AI coding agents (Claude Code) every day as part of the workflow. Our stack TypeScript everywhere Mobile: React Native, Expo, Zustand, Revenue
