Freelancer profile translated to English.

Description

I design digital products that work — especially where AI comes into play.

As a Senior Product & Systems Designer, I help product teams make AI features usable: clear flows for digital products, copilots and LLM interfaces, mental models that don't overwhelm users, interactions that fulfill the promise of AI rather than undermining it.

In parallel, I build design systems for teams that have grown rapidly and now need structure: scalable and documented, in Figma. I also actively use AI coding tools for rapid prototyping and building apps.

I work remotely or in Hamburg, on a daily basis or project by project.

I also work with international teams in English, Spanish, and Russian.
