Avid Emacs and Vim hacker; I use Emacs with Evil to get the best of both worlds.
I write mostly in Java, Python, Javascript, and C, but I dabble in Clojure in my free time. I specialize in distributed systems like Hadoop, HBase, and Cassandra. I'm of the firm belief that code is meant to be read rather than written, and try to make my code and commit history as maintainable as possible.
