I welcome contact via email.
I use twitter occasionally. Please don’t try to contact me directly via twitter though. I may not see it for weeks.
I am self-employed ICT consultant and am available for programming and related work to do with computer interfacing, (embedded) control applications, and private tuition for individuals or small groups who wish to learn or further their knowledge in Linux command-line use, C programming and Interfacing on the Raspberry Pi, Arduino and similar platforms. (And after dinner speeches of-course 🙂
