about me

Hi, I'm Mark.

By day, I'm a software engineer based in Clutch City, and I build applications for the web, mostly with Javascript. Mostly.

Outside of work, I write poetry, prose, and screenplays, build games, and collaborate with friends to make music and films. I also take an embarrassing number of photos of my dog, Gatsby, and can quote nearly all of Jurassic Park.

Yours truly.
