Limulus polyphemus is the Atlantic horseshoe crab. Supposedly, limulus in Latin means “a little askew.”

That’s me. I write software. I live in Tucson, Arizona where I’m a Senior Programmer at small-ish web development shop that works with the alternative press. I mostly write in Perl, JavaScript, and a language for hipsters you’ve probably never heard of. My latest programming hobbies have been related to Node.js and iOS development with Swift. I also know C and Objective-C. I like to pretend I don’t know PHP.

You might also know me from TucsonJS, a monthly JavaScript meetup that I am co-organizing.

Here are some other places I put stuff.

I’m also responsible for, a URL shortener and bookmark indexer circa 2008. It continues to run on its own without much intervention, thanks in part to it being designed from the start for scalability.
