ABOUT

Turning research
into clarity

I'm Denise, a product designer with 10+ years of hands-on experience creating products across Europe, Japan, and beyond. I'm drawn to problems where data and human behaviour intersect, designing interfaces that surface what matters and remove what doesn't.

For me, design goes beyond solving problems, it's about empowering people. My process is research-led and decision-heavy: I document the why behind every choice, so the work holds up beyond the handoff.
