Francis Shanahan is a senior software architect with more than ten years of industry experience. He bought his first computer when he was 12 years old (an Atari 130XE) with money saved from a summer job. Within a month, he had written his first game. He specializes in new and emerging technologies in the areas of Web services, the user interface, and digital identity. Most recent examples are the Windows Communication Foundation (WCF), Windows Presentation Foundation (WPF), and CardSpace. He has led several multimillion dollar engagements of Fortune 50 companies through the full project life cycle. He has published numerous articles in both paper and online media, including Microsoft's MSDN Web site. When he's not building prototypes and messing around aimlessly on the computer, he enjoys cutting dove tails, the pentatonic scale, crystal oscillators, breaking 100 with his Callaway, and spending time with his family.
