I am a retired television/radio broadcast engineer. For a short time I worked as a professional photographer and photography remains my hobby, primarily landscape and architectural, with some astronomical work thrown in. In later years I added computer/network administration specializing in closed captioning systems. I taught junior college for a couple of years, and I still drive a car with a manual transmission.

Windows, Apple, and Linux computer operating systems including low level administration. Database design and management. Technical photography. I've forgotten more about broadcasting than I care to think about.
