    Expert Project Manager and Web Developer

    Bulgaria - Last active: 2 days ago - Tests: 4 - Portfolio: 2

    I've worked as a Web developer (mostly in PHP 5/MySQL although I started in Perl and I've also done some Ruby on Rails) since 1999 (yes, there was a World Wide Web back then) but I've been a project manager in the past years. I'm looking for some extra work so I can keep my development skills in shape (and because I still love programming).

    *nix geek

    Russia - Last active: 9 days ago - 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).
