Builder of Things

Putzbrunn, Germany, Europe

I build things — software products by trade, everything else by hand.

It started with building the school’s website. By 2011 a friend and I were building a Zen To Done iPhone app with web tech and PhoneGap — product, design, marketing, code, everything. Being self-taught, we just thought that’s all what programmers do.

I got into open source early, contributing to Hoodie, then creating semantic-release and later Greenkeeper. That work took me around the world speaking at conferences and led me to co-found .concat(), a web development conference in Salzburg.
