Zone7 Engineering vs Blue Sparq: overview
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.
Blue Sparq
Blue Sparq was founded in 2008 and is headquartered in Cape Coral, Florida with 20 employees. The firm's stated specialization in control system design and manufacturing means engineers on staff have specifically worked the intersection of firmware and physical mechanism control, a narrower skill set than general embedded firmware alone. For a hiring buyer building a product with real physical actuation, that concentrated experience is worth more than a generalist team's broader claims.
