I build software for a living and random ideas for fun. I enjoy learning, figuring out how things work, and making them better.

When I’m not doing that, I’m lifting weights, exploring new places and food, or trying to brew the perfect cup of coffee. I also skate, play football, and get a little too competitive over board games.
