    *nix geek

    Russia - Last active: 11/17/2014 - Tests: 7 - Portfolio: 1

    Over the last 10 years, I was working with *nix-like OSes. I started from FreeBSD and OpenBSD, and now I use mostly Gentoo Linux. I have developed a big bunch of parsers/small scripts, configured a lot of different software. I have experience with a few different programming languages, mostly Python and bash. I've tried myself in web development (using flask, mongodb, a little of jQuery, etc). At my main job I work as a DevOps/Systems administrator. I use Ansible, ElasticSearch, Gitlab with Gitlab CI, pacemaker, docker, and many more cool things! I also mentor junior developers. Right now I need some extra money, so I'd love to do the following: 1) Ongoing sysadmin stuff. RAID, gmirror, software installation, compilation 2) Automation tasks with Ansible 3) Work with docker containers, write dockerfiles. 4) Do some Python coding to glue things together I can dedicate a few hours every day with more hours on holidays. I usually work between 7-10am CST (8-11am EST).

    United States - Last active: 09/20/2013 - Tests: 7

    I have spent the last 20 years working with Linux and Unix servers in a system administration capacity, since I first discovered Linux in 1993 to the present. I have worked in academic, ISP, and large enterprise environments. I am familiar with administering all basic internet services such as DNS (BIND), e-mail (sendmail, postfix, qmail), FTP (various servers), and web servers (primarily apache). In my capacity of system administrator over the last 20 years I have also become an expert at Perl and shell scripting, from automating small jobs to creating more complex integrations between other tools. I am highly regarded by my peers that I have worked with, for learning new environments quickly, being able to implement anything in Perl, knowing obscure tricks in Linux, etc. If your need touches any of those things, I can help you and help you quickly.
