An Interaction Prototyping Designer who cares about crafting surprise, delight, and love. Previously at Waymo, Google, and Pinterest.

Oh, and things took a turn. I left DoorDash for a new adventure, looking forward to October.


I'm Zhendong Li, but I go by Justeen Lee. For me, design should instill surprise and delight in the process of creation, and lead to products that crack smiles when people are using them. To do that, I carefully, rigorously, and harmoniously choreograph together intentions, motion studies, sensor I/O’s, lines of code, and means that can bring a simple thought to life, so that they are able to touch it, feel it, and immerse themselves in something natural, joyful, and heartwarming.
