I design clear products for complex workflows.
Three years at the Science Based Targets initiative, redesigning the validation workflow thousands of companies use to submit climate targets. Before that, fintech at Universal Investment. I work where the process is regulated, the data is dense, and being wrong is expensive.
Selected case studies
Enterprise workflows, design systems and 0-to-1 products. Three in depth, with the research and the decisions that did not survive it.
A 14-step climate-target validation workflow, redesigned down to 6 steps, for an enterprise platform processing targets from thousands of companies worldwide.
A 60+ component system built from scratch for a global climate-tech platform. It unified three product squads, and engineers moved to pulling components by name instead of rebuilding them per screen.
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 with pilot users.
An independent product I designed and took to functional builds with AI-assisted tooling, to test behaviour and platform constraints beyond a static prototype.

How I work
I am a Senior Product Designer with 7+ years designing B2B and consumer products across climate technology, fintech, digital assets, healthcare and logistics.
Where I do my strongest work
Complex products where people read dense data, complete regulated workflows, or make decisions that are costly to reverse. Seven years across enterprise software, climate technology, fintech and AI-assisted products, leading work from research and problem definition through interaction design, design systems, usability testing and delivery.
How I use AI tooling
I use AI-assisted development tools to take my own designs to functional builds. Anstoss went to Android and iOS this way; Attestloop runs as a live scanner. Testing real product behaviour finds the problems that a prototype hides, before implementation gets expensive.

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.
