Open to senior design and design-engineering roles · Berlin and remote (EU)

I design complex systems.
Then I build them.

Senior product designer and AI design engineer in Berlin. Seven years on complex B2B and B2C products across fintech, climate, health, and enterprise: dense data, real regulation, little room to guess. I don't stop at Figma. I prototype in code, design human-in-the-loop AI, and ship.

About

A designer who can read code, run a sprint, and ship.

Senior product designer and AI design engineer in Berlin, seven years in. My work lives on platforms heavy with data and rules: fintech, climate, health, and AI, in-house and at agencies. I design the system, prototype it in code, and ship, most recently Anstoss, an Android app I built solo.

How I work

Research comes first. I run interviews and usability tests before I open Figma. Then I prototype in code, not just Figma, using AI build tools like Claude Code and Cursor to reach a working build fast. I stay with engineers through the build, because a handoff doc has never shipped a screen on its own.

What sets me apart

I design and I build. I've owned an entire enterprise platform solo, shipped my own Android app end to end, and designed AI features where model confidence and human oversight were the real problem. I write production code, understand cloud infrastructure, and hold Scrum, Product Owner, and Google Cloud Security certifications.

AI & Data UX

Human-in-the-loop AI: explainability and confidence UI, agent-driven workflows, and document-heavy review where people trust, audit, and override the model. I build these features, not just spec them.

Anstoss · Android & iOS

Designed and built a football squad-management app for Android, solo and end to end: native Material Design UI, a floating overlay that surfaces key actions over other apps, and AI features that surface squad insights while keeping the user in control. Shipped against real platform constraints, overlay behavior, app signing, deep-link verification, using AI build tools (Claude Code, Cursor, Codex) to go from concept to working build fast.
