My name is Raphael, I'm a product engineer and full-stack developer from Hamburg in Germany. With a team of AI agents I take products from idea to release: I bring the product thinking, the eye for UX and UI, and the technical architecture. The agents write most of the code.

The proof is live in the app stores: my own apps have passed 1 million downloads with excellent ratings. My expense-sharing app Splittr runs on autopilot, with AI agents fixing bugs, building features, testing on real devices, and shipping releases.

That only works on a solid foundation: over two decades of native mobile, web, and backend development with TypeScript, Swift, React Native, Node.js, Next.js and more. You can only direct what you deeply understand. I've also been tech co-founder of a health-tech startup and brought LLM applications into production for enterprise clients.

Whether you need someone to lead product development end to end, bring AI agents into your team's workflow, or a senior developer who raises your team's velocity: I build software that ships and lasts.
