Me and my family

Hi 👋

I’m a designer and builder based in Düsseldorf, Germany, where I live with my small family.

Although I am a trained designer, I've always felt like a generalist at heart. When I notice a problem, I can't help but dig in, understand it, and try to solve it. I like getting my hands dirty and moving things forward.

I enjoy connecting business goals with design decisions. I love building things, especially software, and I’m happiest when I can watch a product grow and become more useful over time.

I’m genuinely interested to find out what people need, and I believe strong user research and honest conversations with customers are the best way to get there.

Outside of work, I love spending time with my daughter. Music, swimming, and cycling keep me balanced. I have a soft spot for interior, architecture and how cities are shaped — probably connected to my work in some way.

I’d be happy to hear from you.

Cheers,
