I am an engineering consultant specializing in the design of embedded software and hardware, from concept to production. I have over 20 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 design of turnkey solutions or to compliment your existing design team where needed.

Experienced in all aspects of Software Development: Conception, Requirements definition, Use-case analysis, Software/Firmware coding and testing, System integration, Source code control and Customer support.

Goal-driven and enjoy seeing a system or product come alive and fulfill its intended purpose.
