    Russia - Last active: 2 days ago - Tests: 4

    My main goal is to deliver results that you needs. Currently I have more than 2 years of Rails development experience. Working remotely isn't hard for me. Previously I've wrote a code in university(basic knowledge) on 10+ languages (java, c#, perl, haskell, ASM, ... etc). Now the favorite one is Ruby. Can perform a wide range of works(related to web/rails), from setting up server (nginx, puma, unicorn, mina, capistrano) to write some frontend code(AngularJS). https://github.com/AvaelKross http://stackoverflow.com/users/2252437/avael-kross https://www.linkedin.com/profile/view?id=217116757
