I have extensive experience in the online gaming industry, focusing on adminsitration, server engineering, and DevOps.

    I built's infrastructure.

    United States - Last active: 10/12/2013 - Tests: 3

    I'm googleable( I'm located in Utah, I'm willing to relocate, but strongly prefer not to live in CA/NY and I find I'm most effective when working remotely. I've spent the last 8-ish years working for isoHunt as a sysadmin/systems engineer, with crossover into network administration and purchasing. I was Gary Fung's first hire, I've rebuilt isoHunt's infrastructure from scratch 3 times (server4you, toronto dc, stockholm dc), and I ended up recruiting 3 other staffers. Most of my experience is in administering Gentoo Linux, but I'm also familiar with Debian and .deb/apt based distros (Ubuntu and a few arm/mips releases for embedded equipment). I've worked with: linux kernel (I can compile custom kernels to fit what you're using the machine for) linux-vserver keepalived (managing ipvs) iptables/ipset/iproute2 zebra/quagga JunOS (Juniper J6350) git (use, gitosis/gitolite/github repo management, hooks) svn (administration, use; I prefer git) php (fpm/fcgi configuration - I'm not a developer, even if I can identify bugs) xcache lighttpd nginx (not a fan, but I can make it go) apache2 memcached mogilefs MySQL/Mariadb lvm mdraid grub/grub2/uefi nagios This is an incomplete list. If there's something you'd like to know if I've worked with, feel free to ask. I'm also not limited to the above, I'm willing to learn pretty much anything (and actually have some interest in looking at implementing some newer takes on the above technologies). skype/gtalk/yahoo/freenode: infowolfe
