Clojure hacker and frequent hanger-out in #clojure on freenode, where I also go by amalloy. Substantial experience with C, Java, Unix, and PHP as well, but Clojure is the one that's most interesting to me.
Cofounder and primary maintainer of 4clojure, a site for learning Clojure interactively through puzzles ranging from simple to quite challenging.
