I'm more interested in the tech-stack you're using - if willing to share!
On the front end, I rolled my own custom framework. I use Handlebars for templating and various mini-libraries for some functionality (shout out to Modernizr, Isotope, and Bespoke :) in addition to jQuery. For CSS I use Compass/SASS. I actually wrote a blog post about it (http://blog.mightyspring.com/post/58803131171/purposefully-a...)
I think that covers it!
