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.

I write puzzles and do organizational things for Galactic Puzzlehunt. Some puzzles that I've authored or coauthored that I am proud of include Road Trip, Unsafe, A Crossword, and The Galactic Conference. I hunt with ✈✈✈ Galactic Trendsetters ✈✈✈ during Mystery Hunt.

I also write crossword puzzles. I've been published so far in the Wall Street Journal and the Puzzle Society Crossword.

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.
