I am an electronics engineer and started working with computers in 1968. I was in the TV repair business, designed control systems for production machines and built cable-tv-systems for small villages. I began teaching adults around 1972 (electronics for electricians and plumbers), gave computer courses (on Commodores and PCs) and later gave business courses. I was QM, CTO, CIO and CISO of a vocational training institute for 25 years. For about 10 years I was camera-reporter for various TV stations too. I still like to work with video-editing and color correction (daVinci Resolve). Since 2015 I am retired and do some translations mainly for the RaspberryPi Foundation and a software named "Story Architect".
