Chris was brought on to build production firmware for a medium complexity machine tool, including motion control, firmware deployment, sensing and communications. All of the low level functionality and interfaces. He created a well abstracted, thought out, and maintainable system with clear intent and clear interfaces. Basically everything you could ask for from a firmware system. He was transparent, clear and exceedingly diligent throughout the entire process, and worked with all involved easily, building and replicating failure and test cases with clarity and rigor.
