After years pondering the question Where are we? I now work with data science and machine learning in Oslo, Norway.

Earlier, I’ve played with everything from Basic, Awk, Java and C to Assembly. Now, I’m lucky enough to do most of my coding in Python. Other favorites include board games, hammocks, square roots and skiing (preferably up-hill). In my spare time I also have the pleasure of teaching kids to code.
