DE Design Works vs Zone7 Engineering: overview
DE Design Works
DE Design Works was founded in 2002 and operates from Chesterfield, Missouri with a team in the 11 to 50 employee range. Firmware has been a core, continuous practice since the company's founding rather than a service added later, and the team's rugged industrial, medical, and military application experience means its engineers have handled the specific constraints those product categories impose, not just general firmware work. For a hiring manager staffing a ruggedized or regulated product, that's the kind of narrow, verifiable experience worth checking directly.
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.
