I'm a great fan and supporter of open source/free software. It's interesting that I got introduced to open source while at IBM. I taught classes and provided workshops using Eclipse, Linux and other free software. And we actually encouraged its use. After leaving IBM I began looking for an open source project to get involved in. That led to Drupal.
I've been doing Drupal since 2009, beginning with D6. You'll find me Thursday nights with other Drupalistas at the Dojo. And you'll find me on drupal.org as Gippy.
