ZhuangZi is a physicist, engineer, firearms enthusiast, and champion of human rights big and small. He has a background in quantum optics, material science, machine design, biochemistry, and beer. ZhuangZi was dabbling with home-built (3D-printed and otherwise) firearms when Cody Wilson started DefDist - an organization created to decentralize firearm design and manufacturing. When Cody got cold feet, turned DefDist into a private company, and stopped firearms development, FOSSCAD was spun off and ZhuangZi jumped in head first.
