I am a passionate diver and hacker living in Nijmegen in the Netherlands. My friends call me “sebas”.
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.
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 am a core developer and architect of Plasma, a Free software project offering a graphical user interface for laptops and mobile devices, much like Microsoft Windows and Apple’s MacOS. I have professional experience in executive roles in both, not-for-profit organisations, as well as companies. I enjoy programming C++, Python and QML and a few other programming languages. My focus areas are hardware integration, graphics and especially multi-screen support, mobile devices and user interface design.
I have a university degree in management sciences, experience in managing agile software teams and software quality management.
