hi.
i'm
shan-wei.

I'm an engineer working on the Internal Tools Team at Juul Labs, where I build infrastructure that power product research, testing, and formulation. My background is in electrical engineering, robotics, and control theory. Here you can check out some of the things I'm working on. Please enjoy.
