GrouponWorks - The primary business development site for Groupon.
As this site is a constant work-in-progress, but has gotten to a point where I can honestly call it finished. I built this site from the ground up using a very customized foundation of the Drupal content management system. This site was designed by Lucian Slatineanu, a design contractor at Groupon, and developed solely by myself using PHP, SQL, HTML, and CSS.
Throughout the progression of this site, I have been challenged by several tasks, one of the most complicated of which was my being new to drupal, but I was able to overcome all of those and build a sturdy website, one that has never crashed, even though it is our second most visited site, seconded by groupon.com, of course.
Feel free to take a look around and let me know if you have any questions. As this particular site has taken up quite a lot of my time at this job, this will not be the first post on it, there is more to come.
