I own my own company performing penetration testing for computer systems, networks, applications, etc. That pays the bills so I can buy lots of Particle products, along with Arduino-based products and all of the trimmings that make up the IoT world. In the old days I earned a B.S. in Info Systems and a M.S. in Computer Science. I was a Cisco CCIE back when there were only 4 digits in the certification number. Big fan of reading, movies, and getting those last inefficient bytes out of my programs.
