I run a 25-person company in Boulder, Colorado (http://appliedtrust.com) that has been committed to Opensource for the 10 years we have been in business. Linux, Drupal, PHP, and MySQL/MariaDB hold special places in our hearts.

I am working on:
A module to automate infrastructure jobs (like code promotions, httpd restarts, and other batch jobs): http://drupal.org/sandbox/nmcclain/1186638
A module to send bulk SMS messages: http://drupal.org/sandbox/nmcclain/1193460

I am a Drupal evangelist!
