An interactive map of the official and unofficial trails ("Trampelpfade") on the Uetliberg (the 870m tall hill rising above Zürich).

All my hikes (and via ferrata, fell running, mountaineering, ski tours and snow shoe tours) in Switzerland since 2013 on a single interactive map.

Website with stats and facts on the annual all-time music chart of Belgian radio station StuBru. Fully open source (VueJS frontend, Scala/Play & MySQL backend).

An online version of the game Concept (original by Repos Productions). Source code and technical details can be found in the Github project.

In 2013, I obtained a PhD in Mathematical Logic from the University of Leeds. My full thesis was titled "Notions and applications of algorithmic randomness" (pdf, 801 kB).

• More mathematics
• Meer wiskunde

Currently defunct, as the SLF unfortunately does not publish the snow maps into their archive anymore since 2021.
The SLF is the Swiss institute for snow and avalanche research. Each winter, they regularly publish maps charting the snowfall and snow depth across Switzerland. This web page aims to make the maps from the SLF archive more accessible.
