Hi, I'm Roos.
I create products and interventions to improve behavior.
Originally from the Netherlands, I've spent lots of time traveling and working from various locations around the world. I'm currently based in Amsterdam and open to remote work both internationally and in the Netherlands.
When I'm not working, I enjoy baking sourdough bread, cooking for friends & family, doing sports, reading, or traveling and spending time outdoors.
