My name is Oksana Shchelkina. I'm a Backend developer using Ruby and Ruby on Rails. Currently I work at Traveltech company and my responsibilities are to develop secure and speedy application for tour's booking and optimize code for performance and reliability. I also successfully mentor interns, teaching them Ruby and Ruby On Rails to become full fledged backend developers.
