    Network Engineer (CCIE), System Administrator (FreeBSD/Linux)

    Russia - Last active: 2 days ago - Tests: 6

    I've started as a FreeBSD (and later Linux) system administrator in 1998. This included configuration and tuning of operation systems and various unix services as well as writing custom scripts to automate work and monitor things. Since 2003 my primary area of expertise switched to planning, building and operating networks, mostly based on (but not limited to) Cisco products and solutions, that's why I became CCIE #22125. However, unix-like systems are still part of my life and currenly becoming more and more important for me.
