I design complex systems.
Then I build them.
Senior product designer, seven years on data-heavy fintech, climate, and AI products. I prototype in code and ship.
Research in, shipped product out.
Five projects in depth. Each one shows the route to the solution, not just the finished screen: what the research forced, what I explored and rejected, what testing made me change, and what each decision cost.
A club app for amateur football teams. I owned it end to end: the bet, the feature gate, what to refuse, how far the AI is allowed to go, and the code. Live on Android and iOS in each club's own colours.
A live compliance scanner. It names the exact clause a product is breaking and writes the fix: evidence for an auditor, a patch for a developer. I designed it and shipped it, and it now covers code and AI systems too.
A 60+ component system built from scratch for a global climate-tech platform. It unified three product squads and cut design-to-dev handoff by 40%.
Lead product design for a lost-and-found platform for Europe. 47 screens with AI matching, ownership verification, safe meetups, and a gamified return flow, across B2C and B2B. Now in TestFlight, live July 2026.
A 14-step climate-target validation workflow, redesigned down to 6 steps, for an enterprise platform processing targets from thousands of companies worldwide.

A designer who can read code, run a sprint, and ship.
Senior product designer and AI design engineer, 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.

What the people I worked with say.
Unedited except for length. Each one is a public LinkedIn recommendation, with the working relationship stated.

If the problem is hard,
I'm interested.
I'm open to senior product design roles anywhere in Europe, with a soft spot for fintech, climate, health, and AI. If that's the kind of work you have, let's talk.
