Since 2009, my career has been Drupal websites. Drupal versions 5, 6, and primarily 7 have been my bailiwick. Prior to 2009 I was a system engineer writing device drivers, then Java servlets, then LAMP websites.
On November 19, 2015 Drupal version 8 was released. This website is now re-released as a Drupal 8 site.
Drupal 8 is largely unformed at present writing. The simplicity of this site enables its existance at this time.
I can help you develop your Drupal 7 or 8 site. I will debug any Drupal 7 site. Contact me.
