UX & AI PrototypingCologne, Germany · 15+ years
Most ideas die in slide decks.I build them instead.
Click it, break it, then decide. I help product teams find out whether an idea actually holds up — before they spend a quarter finding out the hard way.

About
Hello. I'm Christoph, a designer and UX lead based in Cologne, Germany.
Fifteen years in, I still like the same part best: the moment an idea stops being a discussion and starts being something you can actually use.

Practice
AI Prototyping
Working software as the medium for thinking. I build functional prototypes with AI tools — real interfaces, real data, real flows — so decisions rest on something you can click instead of something you have to imagine.
- Production-grade prototypes with v0, Cursor and the AI SDK
- From prompt to clickable product in hours — empty and error states included, not just the happy path
- Introducing AI-assisted prototyping into design and product teams
Designing for AI
AI products break the rules interfaces were built on. They are probabilistic, they get things wrong, and they have to earn trust. That needs its own design craft.
- Trust, transparency and graceful failure — making model behaviour legible to the people using it
- Prompt engineering as an interface design discipline
- Conversational and agentic interaction patterns
Strategy & UX Craft
Prototypes only matter if they answer the right question. The strategy and research work is what makes sure they do.
- Product strategy, journey mapping, opportunity framing
- Qualitative and quantitative research, usability testing
- Information architecture — and raising UX maturity inside organisations
