Hi. I am a professional Linux trainer, and thanks to the magic of the internet, I teach Linux classes literally the world over from the comfort of my living room. I got involved with Linux way back in 2006, and have been working with it ever since. I am also a Linux security researcher for an IoT security company. I have worked on many aspects of the Linux system programming stack, including Bash scripting, system programming in C, kernel internals, device drivers, and embedded Linux work. My Linux passion feeds well into my passion for teaching these topics to engineers, which I have done for well over two decades now.
