I make software to help people learn and achieve more. Since 2015, I’ve worked fully remotely at Nutrient (previously known as PSPDFKit) and been an organiser of NSLondon.

For a few years, I was a digital nomad, but these days I don’t fly and spend my time near London or Innsbruck. When I’m not doing computers, you’ll find me ice skating, wakeboarding, skiing or snowboarding.
