    I really like Linux and Unix. I first read about these systems in magazine while studied in school in 2000 year. I longed to know more about it, but at this time I could not find it in my town. Everywhere was Windows... I hadn't computer and Network. I watched in the cinema at the hackers who quickly knock on the keyboard and typing commands in a black console, and was sure that someday I will like they :) Then I finished schooling and entered the University, the faculty of information technology with the hope of finding it. But even there it was absent... I finished University at 2008 as an engineer, system programmer. But without experience immediately after receiving the diploma I was hired as an engineer for software testing (QA). But there I finally found a Linux! My first distributive of linux was self-compiled from sources - Gentoo. I install it to my home desktop 3 weeks, because I had never worked with Linux. I deliberately chose Gentoo is to get in-depth knowledge and experience. So, I began to delve with these systems in 2008. First as an QA-engineer, then I was promoted to system administrator, because self studied to working with linux. In my work I was manage other Linux-systems (debian, ubuntu, centos, rhel, also Sun Solaris and AIX). But after Gentoo and QA's habit to delve in everything... for me very easy was manage these servers with running services ( some proprietary and opensource programs, such as Squid, Bind, Postfix, Apache, Mysql, IBM DB2, IBM WebSphere, Atlassian Jira, Zimbra, etc) . Therefore in 2013 I came to other company as an experienced specialist in Linux. Here I work with over 40 servers of clients (mostly specialize in Nginx+PHP-fpm, Apache, Postgresql on Ubuntu/Debian/CentOS, but had to deal also with other systems and technologies) Yep, now I can very quickly knock on the keyboard blindly and write commands in black console, such as hackers in the cinema :) So, I'm evolving a professional with over 5 years experience and after this story are easy for me any Linux- and Unix-systems and any software on it. I like this my interesting job and I get fun with it. If you need for your projects the someone, who could to understand and show you the insides of your systems or solve interesting problems in any level, also on-going support for the smooth work of your servers, then I am at your service. If you try to work with me now, while I do not have feedback, rate will not grow as fast for you, than at time when I will have feedback Regards, Alex.  less

    I have been working in IT for over 15 years now, and loved almost every minute of it. While I have experience with everything from Netware to Windows to Aix on the administration side, I primarily specialize in virtualization now, particularly using VMWare (though I have used Hyper-V more than I care to remember). To help back up that systems experience, I also have extensive experience managing storage hardware, particularly EMC and Netapp SANs and Brocade and Cisco MDS fiber channel switches. Combine this with my experience managing network hardware in one of the largest military campus networks in the Middle East, and everything in the datacenter is covered. I started my certifications with Novell and Microsoft, but have also received certifications from Comptia and Cisco at times, along with training from Netapp. Whether you are looking for someone to handle a small server issue or a full infrastructure upgrade and migration, my skills, experience and talents fit the bill. I hold VMware VCP-DCV and Cisco CCNP:DC certifications, among many others  less
