I design and implement automated testing systems, including specialized APIs and the VMWare-based virtualization environments designed to support them.
As part of getting a BA in psychology back in the day, you had to have several statistics courses, industrial psychology, human factors, ergonomics and it was strongly suggested that you become familiar with symbolic logic. Neurophysiology, particularly neuronal functioning, was popular too. Had psychology research funding not dried up after Reagan was elected, I might still be in a lab somewhere.
Fate had other plans. Unable to find honest work, I took up the software trade instead. That was 34 years ago.
I use my psychology degree every day.
