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
I build design systems that scale across markets, brands and teams. I document them so designers and engineers can rely on them in their daily work.
People First
Accessibility isn’t something you add at the end. I bring research, testing and inclusive design into the first sketch, so products work for everyone.
Leading Change
I’ve led teams of up to 30 people. Today I coach organisations through change, from the first workshop to the board room.
AI-countable
LLMs are fast, but they don’t know your users, your business or why a decision was made. I challenge their results and keep them accountable, with 15 years of experience in what’s worth shipping.
