    Ruby on Rails fullstack developer

    Ukraine - Last active: 1 month ago - Tests: 15 - Portfolio: 4

    Since 2008, I have developed a wide range of scripts, from parser tool to complex social network. I use HTML, CSS and Javascript (jQuery) for client-side programming and various of technologies (Ruby on Rails, PHP, MySQL, SQLite) for server-side. I can't stand still, I need always to improve my skills, learn new technologies, keep abreast of latest IT solutions. I know and have experience in many technologies, solutions such as AJAX, Git, Heroku, Amazon AWS, Stripe, MVC-frameworks, Linux. Much time I worked with Zend Framework. It provides ability to develop websites quickly with high quality, easy to mainteOOPnance. Also I have deep knowledge in Drupal and Wordpress on the developer level ( writing own modules/plugins, making themes ). Sometimes websites requires extra software for working ( for example, Poker site needs poker server to allow users to play online poker ). This software requires deep knowledge of server application development ( multi-threading, high-load stability, client-server architecture ). I use Qt framework for C++ or Java to developing these applications.OOP Lately I love Ruby on Rails framework. It is super simple and powerful framework. I use the best practices to write robust and flexible code - Git for version controll ( branches, yeah! ), unit and functional testing (RSpec and Capybara). I use Linux as primary desktop OS since 2008 year (Ubuntu 8.04). Since that time, I've tried many Linux distros: Fedora, Gentoo and my last choice is Archlinux. All my servers (VPN, Dedicated etc) I've configured by myself, so I have expierence in DNS, POP3, SMTP, FTP, HTTP protocols and daemon's configuration.
