About
Amsterdam
Ilse Vos. Product designer who builds, nine years in.
Story
I studied interaction design in Amsterdam and spent four years drawing interfaces on paper before anyone let me near a screen. The habit stuck: most of my work still starts with a pen.
At Brightwork Studio I learned to ship my own CSS, then moved to Fennick to own one product for three years. Ostra came next, and with it the chance to design a booking flow and write the components it runs on.
How I work
Sit where the work happens.
Research at the front desk, not in a meeting room. Twelve shifts taught me more than any survey.
Prototype in the material.
If it will ship in React, the prototype is in React by week two, so motion and edge cases are real.
Write it down.
One page per decision, one rule per component. Teams read short things.
Experience

Nine years, four places. Each one taught me the next thing I needed: drawing, shipping, owning a product, building its parts.
