    Senior Ruby On Rails Developer

    Russia - Last active: 1 day ago - Tests: 3 - Portfolio: 4

    Hi, glad to see you here! I'm a Team Lead and Fullstack Senior Ruby Developer. I'm specializing on high-level application architecture design, prototyping and writing solid testable code. I'm prizewinner into 2 Upwork coding challenges (oDesk's Coding Challenge and Upwork Code It Up). When I have time I contribute to opensource projects. GitHub - akolomiychuk. I'm Team Lead and Lead Developer in SmartDev. We're a fullstack developers who focus on Ruby on Rails and Yii. Besides that I'm good at establishing development workflows in existing teams - ask me for the case study! One of projects: I and my team created custom CMS and online ticketing platform for Australian company SEMIPERMANENT. Project launched in 2012. At 24 July 2014 it had 5613 sold tickets on events for designers on 3 continents and we continue improving it. I want to make products for real people. So I do not work with projects in which I'm not believe. I put my soul into every project, so it's important to me. The same way I'm not working with projects where the deadline is yesterday. I believe that deadline - it's when someone seriously messed up. I'm - about calm and confident way to move towards the goal. I'm Ukrainian, who live in Siberia - the center of Russian outsourcing. If you see anything how I can help you - feel free to drop me a line! Take care!

    Senior Full-Stack Developer - Ruby on Rails

    Russia - Last active: 08/27/2014 - 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/
