About me

Curiosity is how I work.

I have a background in media informatics and am based in Munich, where I explore the space between technology, interfaces, and design.

I enjoy going deep on unfamiliar topics, especially new approaches to AI, UI engineering, interaction design, and the tools shaping how digital products are made. My projects are how I learn: I follow a question, build something concrete, and share what I discover.
