Jeffrey Sambells?is a graphic designer and self-taught web applications developer best known for his unique ability to merge the visual world of graphics with the mental realm of code. With a bachelor of technology degree in graphic communications management along with a minor in multimedia, Jeffrey was originally trained for the traditional paper-and-ink printing industry, but he soon realized the world of pixels and code was where his ideas would prosper. In late 1999, he cofounded We-Create, Inc., an Internet software company based in Waterloo, Ontario, which began many long nights of challenging and creative innovation. Currently, as director of research and development for We-Create, Jeffrey is responsible for investigating new and emerging Internet technologies and integrating them using web standards-compliant methods. In late 2005, he also became a Zend Certified Engineer. When not playing at the office, Jeffrey enjoys a variety of hobbies from photography to woodworking. When the opportunity arises, he also enjoys floating in a canoe on the lakes of Algonquin Provincial Park or going on an adventurous, map-free, drive with his wife. Jeffrey also maintains a personal website at JeffreySambells.com, where he shares thoughts, ideas, and opinions about web technologies, photography, design, and more. He lives in Ontario, Canada, eh, with his wife, Stephanie, his daughter, Addison, and their little dog, Milo.
