Design Philosophy
Human First
"I don't build for screens. I build for people."
Every pixel has purpose. Every interaction tells a story.
Becoming
Origin Story
Born in Germany and raised between design studios and nature trails, I've spent the past 15+ years learning how to bring structure to vision. I didn't grow up wanting to be a programmer — I wanted to tell stories.
And so I did, with shapes, systems, and eventually code. My background is in communication design, but curiosity led me deeper — into UX psychology, interaction theory, and business design.
Evolution
What began as typography and visual systems became creative direction. What started as campaign strategy eventually turned into AI tooling. I never stopped evolving. I never wanted to.
To me, both sides belong together. Beautiful systems must run well. Elegant code should feel thoughtful. The front and the back are not separate — they are two angles of the same human experience.
