My love is teaching and writing about technical subjects especially programming languages. I have nearly four decades of professional experience working, teaching and mentoring novice in the field. The programming/scripting languages I know is Objective C, Swift, PHP, Python, JavaScript, TypeScript, C, C++, and Java. I have also worked as a Software and Network Engineer for some of the most well known corporations in the world in the past four decades.

My hobbies are playing Golf, reading, travelling the world and still contributing to the open source projects when I have the time.
