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. I use Python and PHP to develop web and shell applications and automation scripts. I am a free software contributor. So i am good at remote working and collaboration tools. I use git and svn actively for various projects.
Daily working at puppet environment with over 200 servers controlled. The areas of my work focus at web hosting environment (Pupper, HAProxy, Varnish, HTTPd, NGiNX, Apache-solr, MySQL, MongoDB, etc.) I worked also in company which use AWS Amazon for e-commerce platform. I was responsible for create scalable environment and monitor performance. During that time create a lot Ruby scripts for easy manage env or speed-up Aazon java tools. I also have experience in the following areas: 24/7 systems, HA Systems, LAN/WAN networks.
