Hi! I’m Jakob. I write software and puzzles sometimes, and make art at other times.

I work at Keybase writing software to make end-to-end encrypted services more widely available.

Sometimes I do various role-playing games, of both the tabletop and live-action variety. I co-wrote a game called Fading Lights for Intercon 2019. It's since run at several other venues.

In the past, I did some computer systems security research at MIT CSAIL.

Other things I like include board games, cycling, climbing, electronics tinkering, and vegetarian cooking.
