Behavioral Designer.
Product Lead. Author.
I design products, services and decision environments in FinTech and write about what happens when we stop thinking for ourselves.
Writing
The Fridge Test
A fridge, thirty seconds – and why visible parts feel like your own knowledge.
The question that breaks sham understanding
One question – and why an imagined listener nods more easily than a real one.
What I learned about good design from doing bad design
A won A/B test – and why neither “frictionless” nor more friction is the answer.

The Illusion of Understanding
Fake news is the problem everyone talks about. Sham understanding is the problem that sets off no alarm.
About
My work starts where a product asks people to make a decision.
Currently Lead Product Design & UX at Migros Bank. Strategy, compliance and user behavior have to align before the first sketch is drawn.
With money, credit and long-term decisions, I use friction deliberately, as a moment in which people start thinking for themselves again.
I write about behavioral design and what happens to our thinking when machines do the explaining.
My book «Die Illusion des Verstehens» is published on 12 November 2026 as a digital edition, in German.
