eBay.com/design
Earlier this year, the design team at eBay worked on a redesign to replace their current design site with a new one. And wanted some pretty complicated interactions to show off the site. After months of work from my initial code to collaboration between designers, it's finally live!
The eBay design team designed the site and pages, I merely provided the code for all pages, their interactions and made it responsive (with help of open source libraries too, of course).
