Web designer Cemile Biyiktay designed the theme and provided me with the assets. I developed a front-end translation with Boostrap(HTML/CSS/JS) from the designer's vision. I then worked with another developer Raymond Berg to implement the design on top of an existing Django platform.
See Raymond Berg's talk where he gives an overview of the redesign project and all of our roles in it: (the redesign talk starts at 7:16 and ends at 40:14)
