Douglas McKechie has had a passion for programming since an early age. He started out by writing QBASIC programs from books in the local library and then creating a replica of the game Chip's Challenge in Visual Basic 4.

Now, with over a decade of experience in the IT industry as a web application, database, and mobile developer, he has worked on some interesting and complex projects for both government and private sector organizations and is currently employed by one of New Zealand's top tech companies.

In his spare time, he likes to play his bass guitar, build things out of wood, play computer games, listen to vinyl records, and he dreams of building a large space ship out of Lego.

He is the creator of Winwheel.js, a feature-packed JavaScript library for creating spinning prize wheels on the HTML5 canvas. You can find more about this at http://www.dougtesting.net.
