Independent
product engineer.

I'm James Fitton, based in Houghton Regis, UK. I design and build web and mobile products, working across product shape, interface, frontend, backend, data, infrastructure, and store submission.

My current focus is ROAM, a swipe-to-discover app live on iOS, Android, and the web. It is designed, built, and operated solo. It shows how I work across three platforms from one codebase with real users.

Around that I build interactive data viz, generative and creative web, and LLM-powered tools. Same approach each time: understand the problem, ship a useful version, and learn from what breaks.

I'm self-taught, and I've learned by shipping. I work quickly, communicate decisions clearly, and take responsibility for the result.

Open to product engineering roles and selective client work where ownership is the point.
