Andrew Psaltis has a wealth of experience in software design, and in the construction of large-scale data-intensive systems. He has been involved in teaching since graduate school and over the last 20 years as a software professional has always been involved in some form of training, I think you would say I am a developers developer. He is deeply entrenched in streaming systems and obsessed with delivering insight at the speed of thought. As the author of Streaming Data  (http://manning.com/psaltis/) by Manning, an international speaker and trainer he spends most of his waking hours thinking about, writing about, and building streaming systems. When he's not busy being busy, he's spending time with his lovely wife, two kids, coaching and watching as much Lacrosse as possible.
