    Senior Full-Stack Developer - Ruby on Rails

    Russia - Tests: 3 - Portfolio: 4

    With experience in programming for over 14 years, I've been doing Ruby & Ruby on Rails web development for the last 4+ years. I love concentrating on the end result and final polish - that's what user will see and interact with. As a result of this thoroughness and attention to detail, my open-source history viewing plugin for Miranda IM (http://addons.miranda-im.org/details.php?id=2995) became Miranda's de-facto standard. In addition to ruby, I know and use the following frameworks/technologies: CSS, AJAX, HAML, SLIM, SASS, SQL (MS SQL, SQLite, MySQL, PostgreSQL), NoSQL (MongoDB). My main expertise is Ruby (and Rails) - I've got 2nd place in oDesk Coding Challenge among Ruby developers. Also, I'm in the top 10% in Ruby and Ruby on Rails tests on oDesk. My projects do deployment, server provisioning and production error reporting automatically. I use Capistrano to deploy projects, Ansible for server provisioning and New Relic with Airbrake or Rollbar to monitor app in production. I can read other languages, like php, java, perl, python, c/c++. https://github.com/artemf/
