About Me

I am a game developer and a passionate pianist. When I first got into AR I was immediately hooked and couldn't think of a better use-case than piano learning. Combining my two passions this felt like a perfect match and I went on to spend the next few years developing prototypes for different hardware and researching digital music education.
