About

I shape brands, make interfaces and mainly focus on building user-centric digital products. In essence; I create, break and prototype. I enjoy designing meaningful products that engage, have a touch of personality and actually work — simple, stunning experiences with great end-user impact. Primarily interested in creative interactions and meaningful animations. I have a basic understanding of software engineering, which supports finding solutions that work for both users and developers.
