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 London, England, he currently works at Yahoo! Inc, as the Director of Engineering for Flickr, in San Francisco, California. He's been working on Flickr from the day it started development (on his laptop) to the present day (where it's now the "Offical website of the Internet"). In 2006, he wrote the book Building Scalable Websites for O'Reilly Media.

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 communitites, 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. And writes biographies in the third person.
