I am a Senior Software Development Engineer on the Exchange Web Services team at Microsoft and one of the authors of the book Inside Microsoft Exchange Server 2007 Web Services published by Microsoft Press. My main areas of focus within the team are in the Exchange Impersonation infrastructure, CAS to CAS Proxying, Restrictions/Search folders and lots of infrastructure work. I have been at Microsoft since the end of 2004. My wife and I currently live in North Carolina with our five children.
