Sjoerd Dijkstra

UX Director & Head of the Netherlands @ App Annie
I love to create & improve digital solutions that humans understand and really want to use. Users are happy and stay loyal, or not and leave. I am designing for more than 15 years on both client & agency side and as a consultant. Besides work, I organize a UX meetup in Utrecht called UXU.
