I am an embedded systems consultant specializing in the design of embedded software and hardware, from concept to production. I have over 25 years of experience solving real-world problems in the creation of hand-held devices, networking switches, robotic manipulators and vehicles, lighting and camera controls, power systems, motor controls and distributed control systems. My experience in these areas allows me to maximize product functionality while also negotiating environmental, packaging and cost constraints. I offer my services in the design of turnkey solutions or to complement your existing design team where needed.Technical Strengths• Embedded software and system design for real-time control.• Control system design, configuration and tuning.• Sensor interface and integration.• Communications and networking over serial buses, ethernet, and wireless links.• Design of bootloaders with custom integration over communication channels.• User-machine interfaces.• Motor control for BLDC, BLAC and PMSM motors.
