Oxalis Design vs Zone7 Engineering: overview
Oxalis Design
Oxalis Design is a Bristol, UK electronics and embedded systems consultancy founded by Alex Turner and Alex Thornicroft, both experienced electronics and software engineers who remain personally involved in client work rather than having moved fully into management. For a client evaluating team fit at the smallest scale, this means the people making architecture decisions are the same people who will be reachable throughout the engagement, not a sales contact who hands the work to unnamed staff.
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.
