Exceed your Expectations I began surprising people while in my teens, and decades later, that hasn't stopped. Whether my next surprise is rescuing a seemingly hopeless system, sending you 50$ refunds for every bug found in my software, turning an everyday report request into the discovery of a new cost-saving business process, herding cats (e.g. programmers) living around the world into becoming a world class team, or helping you learn what you didn't know you needed to learn, I can't yet say. But everyone likes unexpected gifts. I look forward to working with you. P.S. I am fluent in German. In French I have some reading knowledge and a *very* basic conversational ability (French is such a beautiful language, I look forward to having a pressing business need to rapidly become fluent). I used to be fairly fluent in Japanese; someday I hope to regain that as well.
