Linux SysAdmin

Brazil - Tests: 1

I am a Linux Sys Admin with extensive experience in support and installation of Linux servers and data centers for Infoplace. I have more than 7 years of experience in supporting companies in various segments, totaling approximately 200 servers installed. In this role, I was managing two teams, one with three people in Linux support and other with four people in microcomputers support. I was responsible for client relationships and worked directly with the small, medium and large companies support and critical servers. I have much experience with supporting and creating solutions for companies of all sizes, local and remote, with different distributions (CentOS, RedHat, Fedora, Scientific Linux, Ubuntu, Debian), in various environments and types of equipment. Now I'm living in Brazil, but when I have been in Los Angeles for 2 mounths for vacations, I saw a rising up city in my area, so I believe that a remote job would be the best option to start this process, that can soon live and work in los angeles and improve more my skills and contribute to improve for your company too.
