Darrin has been around SharePoint since the Tahoe days. For those that have not been working in SharePoint that long, Tahoe was the code name for SharePoint Portal Server 2001.
Lately Darrin has been working with SharePoint with Windows Phone 7 and Azure. His blog is primarily about SharePoint along with some WP7, Azure and other topics such as Data Entity Framework and Silverlight.
Darrin is a founding member of Aptillon along with Todd, Matt, Maurice, Gary, Dan and Dave. We all work together on some really interesting projects along with some of our trusted partners.
