    Over the past 4.5 years I`m a system administrator on highly loaded projects. I started as junior sysadmin in masterhost, largest hosting company in Russia at that moment, and grew up to very experienced system administrator. For the last 3 years I`m working in one of the biggest internet company in Russia, mail.ru group. In masterhost I used to administrate FreeBSD and Linux servers for shared hosting and VPS hosting. Nginx, apache, mysql. Searching for bottlenecks, mysql, apache, nginx tunning. OpenVZ. In mail.ru group from 2011 til 2013 I was working in storage-team. Over 3000 servers, 12 Petabytes of data (emails, photos, videos, etc). And from 2013 I`m working in go.mail.ru team. Developing cloud infrastructure based on LXC. It`s hard to write all my occupations, so here is skills I used most: Linux system administration(Centos mostly, Debian and Ubuntu) nginx apache mysql redis memcached sysctl tunning for highly loaded servers strace, gdb for very deep debugging kickstart (had developed fully automatic system for servers installation based on ks) puppet, mcollective (orchestration and configuration management. Started puppet from scratch in mail.ru) saltstack (same as puppet purpose, but brand new way of orchestration and configuration management. Our team migrating right now from puppet. Like it more)  less
