In short I am a Linux server and network administrator but its not enough to explain my expertise.
First of all, in Linux side I have expertise with the most used distributions like Debian/Ubuntu, RedHat/CentOS/Fedora family and some other not so ordinary ones like Gentoo, Archlinux.
I manage and troubleshoot large variety of software/applications for example Apache, Nginx, Lighttpd, MySQL, Postgresql, Bind, PowerDNS, Nagios/Icinga, Cacti, Raidus, Tomcat, Squid, DHCP, NFS, Samba, OpenVPN, IpSec, LVM, VirtualBox, XEN, VMWare ESX, OpenVZ and so on. I also have experiences in HTML, PHP, CSS, Js, Perl, Shell programming, scripting.
I have experience on different type of hardwares like Dell, HP, IBM servers, storage and network systems.
In Networks side, I have years of experience in installing and managing networks used Mikrotik, Cisco/Linksys, HP/3Com, Dell, AT switches, routers.
