About

Berlin · UI/UX · Frontend · AI

I work end-to-end: design, frontend, and automation, for founders and product leads who need one person to own the whole thing. No handoff, no agency overhead.

Before going freelance, I spent five years at Native Instruments, first as a Senior Graphic Designer in marketing, supporting 12+ product launches a year, then as a Senior UI Designer in Products, working on audio software interfaces.

I use AI across the full workflow: research, prototyping, copy, and code. Fundamentally reshaping how I work and enabling both speed and precision at a higher level.

Based in Berlin. Working with clients across DACH.
