I have been teaching the Linux Operating System since 2008 at Mesa Community College and have been working with Linux for nearing two decades now. In 2009 I was a contributing author to The Command Line for GNU Press and have served as a subject matter expert for other publishers. In 2018 I was recognized by Red Hat as an outstanding academy instructor. Two of my courses have received Mesa Community College’s Gold Star certification for instructional excellence. I hold numerous industry certifications including AWS, CompTIA, Linux Professional Institute and SUSE Linux certifications as well as blockchain certificates of completions from MIT’s Sloan School of Management and the University of Buffalo. In 2019 I started teaching blockchain and cloud computing. I am an AWS certified instructor.
