Johan Falk is Drupal trainer and developer, currently on leave from NodeOne (studying to become a math and physics teacher).

His Drupal passion is mainly focused on teaching and learning Drupal, and he is a regular (manic) producer of Drupal screencasts. He has written a few Drupal books (one in English), recorded some 250 screencasts, worked on Drupal "skill set" mapping, and some other random stuff. His firm opinion about Drupal Done Right is that you should always use frameworks modules like Views, Rules and Page manager, and all developers should know these modules really well.
