I've been a software engineer for QCS Industries LLC CA, my company, and others, for 20+ years, also a hardware engineer for 10+ years at QCS and SDI at different times. After that I was a Cryogenic engineer at SDI simultaneously. The last 4 years I worked at IBM in West Sacramento, CA on the California Affordable Care Act as a software engineer.
I'm 74 years old but don't look it, that's me at GE in my photo.
Right now I'm working at home making software and design for Arduino boards and DDS (Direct Digital Synthesizers) Frequency modules for Transceivers for my ARRL Rig which I might just be selling when I'm done on the open market. That means starting a new company again.
