Engineer & builder

Eugene Chen

Computer Engineering at the University of Pennsylvania, and founder of Jinke Energy Co., Ltd. (brand name GIENKEE). I build trading infrastructure, manufacturing automation, hardware, and research tooling — systems where correctness matters, alongside the parts of a workflow that can tolerate a model's best guess as long as it says so.
