Over the last 14 years, Phil has proven again and again his ability to get things done, whether it's extending and improving an existing project, or developing one from scratch. He is able to move smoothly between technologies, and has an exceptional ability to dive into a new field and start contributing immediately. He's a great team player, mentor, and thought leader, but also has the discipline to fly solo.
