Cal Henderson

Cal Henderson has been a web applications developer for far too long and should really start looking for a serious job. Originally from England, Cal is the VP of Engineering for Tiny Speck. Until recently he worked at Yahoo! Inc, as the Director of Engineering for Flickr, in San Francisco, California. He worked on Flickr from the day it started development (on his laptop) until April 2009 (when it was the "Official website of the Internet"). Before Flickr, he was the technical director of Special Web Projects at Emap, a UK media company. By night he works for a whole slew of web sites and communities, including the creative community B3TA and his personal site, iamcal. In his spare time, he writes windows software, develops web publishing tools, and writes occasional articles about web application development and security. He promises he's working on a second edition of Building Scalable Websites.
