Interfaces
that endure.
Systems, that last.

Interfaces
that endure.
Systems, that last.
UI Design is good, but with UX it’s best.
My tool is the interface. My real work happens behind it:
decisions users no longer have to make, paths that reveal themselves naturally, and systems that work without explanation.

I am a Senior UI/UX Designer and Design System Specialist with more than 16 years of experience across startups, agencies, leadership roles, enterprise environments, and SaaS products. Working at the intersection of UX, technology, and business, I develop products from the initial idea to scalable design systems that create consistency across teams and platforms. My focus lies on complex digital products where design has a direct impact on quality, efficiency, and growth. I am not interested in the perfect surface, but in what lies beneath it: clear decisions and solutions that work in everyday use, not just in theory.
The following pages present three projects that reflect this approach in practice:
five years of product and brand experience design in luxury retail at Breuninger, the development of AI-powered applications for medium-sized businesses, and the creation of a complex design system. Three very different contexts, united by the same ambition — design that works and scales.
Good interfaces are invisible –
they simply work.
