I measure how peopledecide.
Then I design for it. Product designer with an MSc in Applied Cognitive Psychology. Seven case studies: two research studies, one of them published at CHI, and five products and brand systems designed and shipped end to end.
Design that shipped. Research that changed a decision.
Each case shows the question, the design, the numbers, and the part that didn't go my way.
Psychology for the hypothesis. Statistics for the verdict.
And design to turn the verdict into something people use. The same four steps sit under the research and the product work.
Start from how people actually decide
Cognitive psychology gives me a model of the behaviour before I pick a method. That's what turns "users are confused" into a question a study can answer.
Change one thing, measure it properly
Between-subjects designs, randomisation, a power analysis before recruiting. Simple designs give answers a stakeholder can't argue with.
Turn the verdict into a system
A finding only matters once it shapes the product: the structure, the components, and a design language a team can keep building on.
Show the result that didn't move
Effect sizes, confidence intervals and the null results. The finding that went against me is usually what makes the others believable.
Hi, I'm Matteo.
I'm a product designer in The Hague with a research brain. I led digital UX at Faceland, the Benelux market leader in cosmetic treatments, and before that I studied how people perceive, remember and decide at Leiden.
I remove assumptions before I remove pixels. The same discipline shapes how I use every tool in my stack, AI included: never for the shortcut, always for the outcome.
I like questions where the honest answer is a number with a confidence interval around it.
UX and research
- Generative and evaluative research
- Usability and tree testing

- Information architecture
- Stakeholder management
UI and design systems
- Figma, high-fidelity design
- Scalable design systems
- Component libraries
- WCAG accessibility
- Prototyping in code
Experience
3+ years across research and designAway from the screen
I shoot analog film, produce music and draw. Different crafts, same habit: looking closely at what's actually there.
Music production
Seven years in Ableton Live. Mostly experimental trap, with detours into baile funk, lo-fi and R&B. It's also where PHR-5 came from.
Listen to three beats ↓Analog photography
Film forces one decision per frame. The strip above is straight from the scanner. Hover to bring the colour back.
Three beats, one system for seeing them.
Seven years in Ableton, mostly experimental trap. Each beat drives its own visual, and all three are built from the same parts: one pixel grid, one dither, one set of glitch rules. Only the way they read the signal changes.
- Ink signal level
- Orange transients
- Tear a hit hard enough to break the frame

Have a question that needs a number?
Or a product that needs a structure people can find their way through. I'm open to product design and UX research roles, based in The Hague.
