I am a passionate hacker and diver living in Nijmegen in the Netherlands. My friends call me “sebas”.

Software Development

I 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 been an executive at KDE and am currently COO at Blue Systems, leading and managing the team working on KDE software. I am proficient in C++, Python, QML, Javascript, PHP 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.


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 nitrox diver with more than 250 dives in varying conditions all around the world under my belt. I am currently training to become a divemaster.
Another passion of mine is freediving, a form of underwater diving that relies on my ability to hold my breath until resurfacing.
