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. His experimentation continues to this day, ranging from writing API extensions, learning about IDEs, mobile development and the web. As a consultant, he has worked with a wide spectrum of clients, including UPS, HP, Wintellect and Intel. He is now a staff instructor at LinkedIn Learning, where his content team produces hundreds of technical training courses for software developers each month.
