Martijn van Exel

Hello and welcome to


I am Martijn van Exel. My usual internet handle is mvexel. I am not very active on social media; if you want to hear back, it's best to email me at Other places on the internet where I publish things:

If you're in the Salt Lake City area, find me at one of the meetups I organize: the Remote Worker's Lunch Hour (irregular) and OpenStreetMap Utah (monthly). Or drop me a line, I'm always interested in meeting new people.

Here's how to pronounce my name. Why is "van" lower case?
