I’m Daniel and I’m based in Berlin!
Nowadays I mostly map with StreetComplete while on the go.
I used to work for Mapbox between 2015–2019 on the Open Source Routing Machine and on dashcam and satellite / aerial imagery in the context of machine learning; see robosat.
Since then I have always worked at the intersection of tech and the outdoors.
You can usually find me at geo events in Berlin, Germany, and Europe.
