Thanks for completing the course
I am Muhamad Elkenany and I’m your go-to Unix/Linux systems and maintenance support.
I began with Linux in 2006 and have never looked back, gaining certifications in Linux, HPUX and Solaris. Throughout my career I served in several IT companies and am now at work as a UNIX/LINUX System Engineer, ever passionate to learn and know more.
Along the way, I’ve also gained much experience with virtualization (VMware ESXi , KVM ,VPAR) and storage (EMC, SUN, HP storage products)
I’m happy to share my expertise, and support your needs for more knowledge and information in the world of Linux.
If you are enthused about the possibilities of Linux, it is my pleasure to gain new friends! Please add me on Facebook & linkedin.
My name is Mohamed Nawar
I have worked on Linux since 2007, and have got certified RHCE in 2009, then I have spent the rest of my career working on oracle products related to operating system and storage as a system engineer and also as an instructor, so I have a pretty good experience in delivering these technologies.
As a system engineer I worked at the biggest telecom companies and mobile operators, which was the place that I found the latest high-end mission critical technologies.
As an instructor I have delivered operating system (Solaris 10, 11 curriculum, and Red Hat curriculum) and advanced services courses like oracle sun cluster, virtualization on SPARC machines “Ldoms”, advanced ZFS administration and ZFS storages.
I am very glad to be one of Udemy community, sharing with you knowledge and looking forward to know more from you.
