Hi, I'm Mark.

I'm an engineer primarily interested in programming language design and implementation.

I'm a delegate to TC39, where I'm currently co-championing the pattern matching proposal.

Portrait of me, smiling, wearing sunglasses and a gray shirt. There's some scrubland in the midground. The North side of Mount Shasta rises behind me.

I'm nonbinary. My pronouns are they/them.

I live for ski mountaineering. I also live for music - I'm a guitarist and singer. I keep quarterly playlists on Apple Music, if you want to check out what I'm listening to.

If you'd like to chat, I'm reachable at hover here....
