I design clear products for complex workflows.
Senior Product Designer with 7+ years across enterprise software, climate technology, fintech and AI-assisted products. I lead work from research and problem definition through interaction design, design systems, usability testing and delivery with product and engineering teams.
Selected case studies
Enterprise workflows, design systems and 0-to-1 products. Each case study covers the problem, what I was responsible for, the evidence behind the decisions, and what changed.
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 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 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.

About
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 users need to understand dense data, complete regulated workflows, or make high-impact decisions. I work across product discovery, user research, interaction design, information architecture, design systems, prototyping and usability testing.
How I use AI tooling
I use AI-assisted development tools to turn detailed requirements and designs into functional prototypes. That lets a team test real product behaviour and find problems before implementation gets expensive. The responsibility I hold is product design, not software engineering.
