About

The videos on this channel are largely about web design & development with a good dose of mobile development thrown in just for fun. I started doing web development back in 1997. My current day job is Coordinator of the Mobile Application Design & Development Program at Algonquin College in Ottawa, Canada. http://www.algonquincollege.com/mediaanddesign/program/mobile-application-design-and-development/ I hope that these videos help people learn to love JavaScript as much as I do. For best results it has been shown that watching tutorials at 1.5 speed helps to improve both understanding and retention.
