Rostyslav Ross Safonov

Ruby developer

Really love to use style guides, best practice solutions, design patterns etc. Like to work with and write simple, understandable code. A big fan of using pomodoro time management technique what helps me to rich result in desired timeframe. Always interested in working on new projects in a friendly team. Often work with clients directly (self-manager) without any problems.
