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
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.
Simple by default, powerful on demand
Most people need the main path; advanced options should be there for the few who look for them.
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.
Listen to the loudest complaints
Angry community posts are research you didn't have to recruit for; the Flow Checker redesign started there.
Design inside the constraints
Business, legal and technical limits shape the solution, so I bring them into the room early.
Write it down
Guides and specs keep a team building the same thing, especially when the logic is harder than the UI.
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.
