About me
Hi, I’m Max, a design leader based in Berlin. I designed and coded this site. It shows a selection of my work in product design and UX. Good design, to me, is form and function seen through the eyes of the people using it.
Since 2018, I’ve been working at REWE Digital, where I lead UX for Penny.de and the PENNY App. I led the relaunch of Penny.de, from product strategy and agency pitch to design and launch, and helped build the core UX and development team. With product and engineering, I owned end-to-end UX for the PENNY loyalty program, which has reached millions of signups, and presented it to the CEO of REWE Group. Across Penny.de and the PENNY App, I’ve run 15+ usability studies with 150+ participants together with our UX researchers. Today, our team keeps growing the product, and I take on UX product ownership with a strong influence on the frontend.
Alongside that, I co-founded gearo, Germany’s leading peer-to-peer marketplace for photo and video equipment. As CEO and CPO, I took it from the first idea through a seed round to 20,000+ users and a successful exit in 2024. Building a company taught me to balance user needs, business goals and limited resources, and to learn fast from what doesn’t work.
During my 18+ year career in digital design, I co-created frontends, backends and CMSs for mobile apps, responsive websites, in store media and cashier systems.
I lead design teams and stay close to the work, from concepts and UI systems to interactive prototypes and accessible implementation, making complex tasks easy for customers.
Lately, I’ve been prototyping iOS and Android concepts in code with AI tools like Claude Code, Xcode and Android Studio.
I believe in user testing, lean methods, true MVPs, agile work and collaboration.
For me, that means human-centered design, whether the product is a kitchen appliance, a car or an app: people feel right away when it works and when it doesn’t. That’s what drives me, to do my part in making everyday life better for people.
