    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 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.
