Mechatronics engineer based in Shenzhen. Run a business called Linefox with software that automatically designs test fixtures and an assembly house that builds and ships them out. I also consult for businesses to help them prepare their products for manufacturing and setup their PCBA testing systems. I use KiCad for automated generation of connection PCBs as well as for designing product and/or testing PCBs with the GUI paired with a lot of automated scripts.
