I travel the world speaking at software conferences and teaching of programming topics for corporate clients. On the consulting side, I work with customers like Microsoft, HP, Intel, and Intuit, and I'm part of the Wintellect consultant group. I write for several publications, including CODE Magazine and TechTarget. My current UI obsession revolves around the Silverlight, Windows Phone 7 and WPF APIs. My blog can be found at blog.wpfwonderland.com. I am the author of the free Shazzam Shader Editor for WPF/Silverlight.
