About

I'm a Dutch designer living in Amsterdam, designing digital products that people love and trust.

About

UXpertise

With solid experience in design sprints, design thinking, lean startup, and scrum, plus a strong commitment to online accessibility, I help companies and public institutions navigate their digital transformation journeys.


Zooming in, designing responsive websites, native apps, web applications, dashboards, prototypes, and design systems.


Zooming out, creating digital strategies, customer journeys, information architecture, roadmaps, and fostering strong design team dynamics.

Hybrid UX & UI

I’m passionate about creating smart, user-friendly experiences and eye-catching, high-performance designs.


To boost productivity and provide an early preview of the final product, I combine UX and UI right from the wireframe stage. Creating clickable prototypes throughout the process makes the design journey more interactive and insightful from day one.
