I include everyone – in products that scale with AI.
About
Designing for people – for 15 years.
I’m a Swiss-based UX/UI lead from Langenthal, working with clients in Switzerland, Germany, Spain and beyond. Fluent in English and German, I help large organisations find the right solution for every challenge – with users, clients and stakeholders at the centre.

Focus
What I stand for
Systems over Screens
Design systems that scale across markets, brands and teams – documented so designers and engineers can actually use them.
People First
Accessibility isn’t a feature. Research, testing and inclusive design from the first sketch – so products work for everyone.
Leading Change
I’ve led teams of up to 30 people and coach organisations through design transformation – from the workshop to the board room.
AI-countable
LLMs are a fast, mighty tool. But without the context and experience necessary to see the users, the business, the history behind a decision, it will not produce reliable results. We have to challenge it and keep it accountable. And 15 years of experience in what’s worth shipping.
