Retired electronic, mechanical and computer engineer of 40+ years. I started out designing analog and digital instrumentation systems back in the early 80s, systems programming in C and C++, motion analysis engineer (human motion capture for medical and diagnostic purposes), and then eventually went on to consult to automotive, aerospace, finance, healthcare and insurance companies for 16+ years before retiring as a Chief Enterprise Architect, designing large scale business web clusters for Fortune 100 companies.
