    Senior Ruby on Rails Developer, Technical Writer, Translator

    Russia - Last active: 12/27/2014 - Tests: 6

    Hi, my name is Denis. In a nutshell, I am senior Ruby on Rails developer with hankering and aptitude for creating user-friendly and highly-functional websites using the vast array of state-of-the-art yet already proven technologies. I am experienced in both back-end and front-end levels. Chiefly, I follow the MVC approach utilizing Ruby for controllers, MySQL or MongoDB for models, and HTML5/CSS3/JS for views. I also ably utilize the following technologies: — CoffeeScript — HTML and CSS template engines (HAML, Slim, SASS) — JavaScript libraries (jQuery, AngularJS) — Database engines (SQLite, Oracle) — Version Control Systems (git, mercurial) Besides, I have been working as a technical writer and translator for over 3 years. This experience substantially helps me in my website development activities because producing user's guides and manuals helps me better perceive users' preferences and needs so my end product is always highly customer-oriented. Thank you in advance for your time and consideration. I look forward to working with you soon!
