Ethan Winograd is a software architect living and working in Pittsburgh, Pennsylvania.  His career is a wiggly line spanning VB5 and ASP up through the browser wars to C# and ASP.Net with side trips into Python, Java, SOA and open source.  As an enterprise developer he has survived more than one Sarbanes-Oxley implementation and still managed to deploy working code.  He  has the scars to prove it although when he bleeds, its black and gold.  Known to hand-roll the occasional wsdl, he also writes developer articles and blogs about mobile topics on PayPal's developer networks. When he's not trying to be a husband worth keeping around and a real good dad, he plays a few jazz gigs.  Contact him at his linkedin pageor his page on x.com.
