Embedded Software Technologist

My work in the electronics industry spans nearly 40 years, almost exclusively with embedded software. I began developing software and managing teams of developers.Then, I moved to customer roles, including pre-and-post sales technical support, sales management and marketing. I have presented at numerous conferences, including Design West, Design East, Embedded World, ARM TechCon, and my work frequently appears on Embedded.com.
