Yehuda Katz is a member of the Ruby on Rails and jQuery Core Teams, and spends close to every waking moment hacking on open source. During the daylight hours, he's employed by Engine Yard , where his team works full time on Rails. During the evening hours, he's, well, generally also hacking. He spends weekends traveling, speaking at conferences, user groups and companies looking to learn more about any of the technologies he loves. And, when not doing any of those things, you can find him at a bookstore or theater debating sci-fi, technology and dinner plans with his wife.
