iPhones 4 and up store images in landscape mode and use EXIF data to provide proper rotation when viewed. This is a bit quirky as not all desktop browsers provide fixes, or they may not be streamlined. I remember my old project manager telling me their images were showing up "flipped to the side" during mobile QA testing.
The Features module has become a de facto tool in configuration management in Drupal 7. In fact, most Drupal distributions now utilize Features to export configuration and handle updates to the configuration. There is one pitfall - Features was meant to be a way to export a feature set.
I've been a fan of Platform.sh since it came out, even before I started at Commerce Guys. I'm a fan of using builder tools for constructing projects - Composer or Drush make (latter for Drupal) - instead of putting extra code into version control.
Recently I presented at the Drupal 414 user group in Milwaukee on "Drupal Commerce, Deconstructed" to break down what makes Drupal Commerce and better explain some of its inner workings.

One of the benefits to using Drupal is harnessing the command line tool Drush. If you don’t know about Drush, I advise heading over the the
A recent project of mine has been ContribKanban.com for the Drupal community. The name speaks for itself - it provides a way for contributors to work on Drupal.org project issues queues through a kanban board.
