I am a passionate hacker and diver living in Nijmegen in the Netherlands. My friends call me “sebas”.
I also create software that enables privacy and puts its users in control. I do so in a world-wide community of like-minded people.
I have a university degree in management sciences, experience in managing agile software teams and software quality management.
I love watersports. The ocean is my church.
My favorite pastime is scuba diving. I am an experienced sports diver and not afraid of cold water. I dive a lot in the Netherlands, but also abroad. I am certified rescue, dry suit, deep, cavern and ther nitrox diver with more than 350 dives in varying conditions all around the world under my belt. As of 2017, I am professionally trained to organize, prepare and guide and help educating other
divers as divemaster.
Another passion of mine is freediving, a form of underwater diving that relies on my ability to hold my breath until resurfacing.
