I am also a computer system administrator with of 20+ years of experience. I polished myself using Microsoft and Unix server platforms; seeking a change, in 2015 I switched to the Linux operating system and open source technology in general, which led me to become a Linux trainer. I am the founder and president of the Puerto Rico Linux Users Group (PRLUG).

Please join me in developing the PRLUG and bringing awareness of open-source technology. We will schedule Saturday workshops that will focus on Linux installation, basic administration, and use as a desktop system; these workshops will be taught by PRLUG members starting March 2019.
