Rockstar🎓
Top SchoolPhillip Johnston is a California-based CEO and embedded systems expert with 14 years of experience designing bare-metal firmware, defining software architecture, and taking hardware products from prototype to mass production. He has led or shipped over 20 products and supported 100+ manufacturing builds across defense, consumer electronics, cameras, robotics, and automotive domains. A hands-on engineer who moved from firmware roles at Apple and startups to founding Embedded Artistry, he combines deep RTOS/C and C++ expertise (including contributions to widely used embedded resources) with pragmatic manufacturing and test strategies. Phillip is known for improving development processes, optimizing memory and power in constrained systems, and turning thorny bring-up problems into repeatable, automated practices. Non-obvious: he pairs executive leadership with active open-source engineering—authoring libraries and 150+ technical articles that influence modern embedded development.
