About me

I'm a lead product designer based in Berlin. I've spent 18+ years designing B2B and B2C products, most recently as the first designer at startups in FinTech and conversational AI, where I worked directly with founders and covered everything from research to documentation.

My principles

  1. Start from the workflow, not the screen

    Before drawing UI I map who touches a document, in what order and why — approval policies began as a 26-platform review, not a mockup.

  2. Simple by default, powerful on demand

    Most people need the main path; advanced options should be there for the few who look for them.

  3. Ship the smallest useful version

    An MVP that works with what already exists teaches more than a perfect plan — even an App Store built on Tilda.

  4. Listen to the loudest complaints

    Angry community posts are research you didn't have to recruit for; the Flow Checker redesign started there.

  5. Design inside the constraints

    Business, legal and technical limits shape the solution, so I bring them into the room early.

  6. Write it down

    Guides and specs keep a team building the same thing, especially when the logic is harder than the UI.

  7. Leave the system better than you found it

    Every project is a chance to clean up the design system, the components and the handoff.

My current interests

  • Agentic AI interfaces

    How people configure, supervise and come to trust AI agents.

  • Conversation design tools

    Flow editors that scale from a quick demo to an enterprise contact center.

  • Embedded finance

    Finance tools that live inside other products and still feel native there.

  • API-first products

    Designing for developers and for the partners who build on top of them.

  • Design systems as products

    Treating components, tokens and docs as something with its own users and roadmap.

  • Growing design teams

    Hiring, job grades, mentoring and teaching design to non-designers.

  • Research on a budget

    Getting real answers from interviews, community threads and quick tests without a research team.
