I am a long time programmer. I first learned C Programming when I was at the University in 1981. My professional work has focused on computer graphics/user interfaces, and C is the language I have worked with for almost 3 decades (makes me feel younger than saying 30 years!).
I have worked in the training field since the 90s, and have taught programming at a University Engineering College as well as provided many training seminars in programming, graphics, and UNIX/Linux for large training companies. The majority of my work has involved UNIX/Linux systems. In addition to being a C Programmer I am a Certified Java 8 Programmer, I program in C#, and Tcl/Tk, and have a working knowledge of many other languages.
