JOIN THE BEST COMPLETE LINUX (SERVER/DESKTOP) OPERATING SYSTEM COURSE FOR NEWBIE LINUX USERS!! Hi. My name is Mustafa and I'm the author of the 'Linux Mastery' course. I started working as a network and computer systems administrator since January 2011. I have a bachelor degree in engineering from Alexandria University. After finishing university, I concentrated on learning the Linux system administration. I have many certifications in Linux system administration, network administration, database administration, and some programming languages 'C, C++, and Python'. I have a large experience in working on Linux using RHEL, CentOS, and Ubuntu Linux distributions. I have a desire to teach others and transfer my experience to them in an easy and simplified way.
