We have several Drupal Commerce projects under our belts, including the University of Minnesota Bookstores redesign, which involved a responsive redesign for PC, tablet and mobile devices, followed by the implementation and migration to Drupal Commerce from the legacy site.
We also have strong Magento experience as well, which can be integrated into popular web site platforms such as Wordpress and Drupal. We have experience with the enterprise-class features of Magento, powering a multitude of site backends, along with the Community Edition, which is perfectly adequate for many use cases.
Origin Eight developed a visually appealing Drupal 8 website which included a fully-responsive design, mega menu implementation, integration of an external dealer locator, and content migration from a legacy site. Web traffic from organic search jumped significantly with the launch of the new site.
