I like programming languages [since 1980], hacking on compilers and interpreters [since 1992], and building educational technology [1995–2015].

I like Scala [since 2008]. I’m on the Scala compiler team at Lightbend [since 2015], and I’m the main moderator of the Scala chat rooms.

My Mastodon feed is mainly about programming. All my code is on GitHub.


I’m active on Instagram [since 2011] and Flickr [since 2005].
