Detailed Bio

Walt's enthusiasm for crafting software interfaces blossomed early.

Just a few days after discovering how to move pixels around a computer screen, he was devouring books on the topic of computer graphics and UI design. Before long, he was sharing his discoveries with other technology buffs, a lifelong pursuit that has led to teaching engagements at universities, private training companies, and the international conference circuit. As a consultant, he has worked with a wide spectrum of clients, including Microsoft, HP, and Intel. He’s now a staff author at Lynda.com, part of the LinkedIn family, where his content team produces hundreds of technical training courses for software developers each year.

His current UI obsession revolves around the XAML space; Windows 10 Universal Apps, HoloLens, and WPF APIs. Walt is also an MVP and the author of the free Shazzam Shader Editor at Shazzam-tool.com.
