USA Firmware vs Zone7 Engineering: overview
USA Firmware
USA Firmware was founded in 2011 by Bob Scaccia and operates from Brecksville, Ohio with a team of around 17 people. Leadership brings a stated 150-plus combined years of experience concentrated in a small team, which for a hiring buyer means the average tenure and seniority per engineer is unusually high for a firm this size. The managed design process bundles electrical engineering, firmware, FPGA design, and Linux work, so a client hiring this team gets multi-discipline coverage without assembling separate specialists.
Zone7 Engineering
Zone7 Engineering is a Portland, Oregon electronics engineering practice founded and run by David Ashman, a senior electronics engineer with extensive experience designing digital and analog circuitry around various microprocessors and DSPs alongside embedded C/C++ firmware development. For a client evaluating the smallest possible version of an engineering-hire relationship, this is a firm where the person quoting the project, designing the architecture, and writing the firmware are the same single named individual.
