    Ukraine - Last active: 3 days ago - Tests: 2 - Portfolio: 1

    I specialize on Ruby on Rails and front-end development. In spite of the fact I have got a degree in International Journalism and Translation, I worked as QA and IT Sales for total of 3 years (from 2008) and then moved to web development from Jan, 2012. I have performed both back-end tasks (from basic CRUD to making simple APIs or server scripts) and front-end (building static websites from scratch or developing views with twitter-bootstrap). I believe the experience is formed with the quality of the projects, you have delivered, and not with the years of sitting in front of the laptop. Specialties: ruby 1.9.2+, Ruby on Rails 3.0+, linux and MacOS X environment, unix-shell, Git, SQL (SQLite, MySQL, PostrgeSQL), HTML, Haml, CSS, Sass, Less, twitter-bootstrap, javascript, jQuery Here is link to my github profile: https://github.com/amseledka I do photographs and various design tasks in my spare time, as well as help my friends with Russian-Ukrainian-English translations.
