Hi, I'm a Ruby on Rails developer with deep knowledge in API development, database architecting, TDD, Agile development, DevOps. First of all I'd like to talk about my programming experience. My first professional experience was Ruby language, but before that I learned a lot about C/C++ at Tver State University. So I have all basic skills which university gives to his students: algorithms, math, machine learning, web development, database architecture, mobile development, mathematical modeling, working with signals, computer graphic, security and encryption, etc. Also in university I built an Android application for streaming audio-data between several devices via bluetooth. But first of all I'm skilled in Ruby on Rails. So I have experience in writing pure Ruby programs, I know all main concepts of Ruby language and wherever I write a code, I keep in mind best practices. Most of my projects are coded on Rails, but I have experience in Sinatra too. I experienced with all tools which a Ruby developer meets in real life: redis, mongodb, postgresql, mysql, faye, pusher, heroku, git, elasticsearch, sphinx, eventmachine, ajax, bundler. My experience gives me confidence that I'll find a solution to every task which I get and I'll finish all the tasks on time. As for my front-end experience it is rather big. I know all basics such as jQuery, underscore, vanilla js, html5, css3, bootstrap(and other frameworks like foundation). But I think that I specialized in a back-end development. Anyway I know most tools with front-end development such as haml/slim, sass/less, coffeescript, etc. As for front-end frameworks I'm mostly familliar with AngularJS. Also I have an experience with building drawing tools using KineticJS. In my working experience I did a lot of IE8 bug fixing, so I know some IE8 tricks. I have an experience to be a team leader/manager. I built a coding team which created a huge travel service under my control. So I can analyze problems of an end product, order tasks by priority to meet product owner demands. Also as a team leader I tried to teach my team something new every week.
