About me

For 20 years I am working in the field of UX, Service Design and Strategic Digital Consulting, supporting clients to create meaningful products and to build up, lead, coach UX and Product Teams. In 2020 and after going through a Burnout I quit my job as Director UX of an international Digital Agency to fully focus on some of the major issues we face as human beings and society and to drive change through and within my work.

Being a mountaineer for many years, I see every year how fast the glaciers are vanishing. Being up in the mountains shows me every time how dramatic the situation is and that we all need to act right now. With focussing on Sustainable UX and Design I want to bring my knowledge and experience to the table to help saving this world for us and every being on this planet.

„We need to move from a human to humanity and environmental-centered design approach.“​

The clock is running. We need to get the digital products and experiences more sustainable. And this is also good for business. Not building sustainable products won’t be an option in a few years – consumers want it, regulations will demand it. Starting now is good for the planet, for our children and for your business.
