A Human Interaction Designer who believes products should be meaningful and carrying experience loops of delight, surprise and emotion, previously at Google and Pinterest.

I'm Zhendong Li, but I go by Justeen Lee. Nowadays I'm stealing time for this site and immersing himself in AR + AI + IoT in a grad program at ArtCenter.


I play with series of motion studies, arrays of sensor I/O's, and lines of code to define and prototype interactions between humans, interfaces, devices and systems. With a firm vision of harmonious integration of hardware and software, I strive to visualize and bring aha moments to people around me.
