    I have been working as Linux System Administrator for 5 years. I supply linux management service for my customers. I design and install infrastructures for high-available web applications. Most of these servers use Debian, Ubuntu, CentOS, Redhat and Pardus. I use haproxy as load balancer, iptables as firewall, apache, nginx or lighttpd as web server, mysql as database server. I configure replication systems which have one or more slaves. I deploy applications in different languages like RoR, Python/Django or PHP. I am familiar with php-fpm, php-cgi and mod_php. I am also experienced in virtualization. I use openvz, vserver and kvm for virtualization. I prefer using Debian or Proxmox for host system for virtualization.
