    full-stack software engineer(ruby, javascript, ux, ba)

    Belarus - Last active: 2 days ago - Tests: 5 - Portfolio: 1

    Hi, I'm a senior full-stack developer with huge experience in building high quality projects. I have worked with Ruby / Ruby on Rails for more than 3 years and I have provided the clients with the excellent result. I keep up with the times and I think that the future belongs to the mobile web. When developing, we have to think about the scalability of the product: separate application on api and the client-side (the client for the web app for iOS, android, etc.) to optimize the load on the server and provide the user responsive and modern interface. I think that Ruby on Rails an ideal contender for the best framework for the api. I have the skills in the front-end (native javascript, html5, css3) and wide experience in the developing of single-page applications and the applications customized for to work in mobile browsers. For this I prefer to use ember.js and backbone.js. Recently had a great experience in prototyping (usability and business analysis) and the development of the MVP for software startups. In this regard, I I would like to deal with interesting projects and new technologies, such as: Loopback.io, Sails,js, react.js, angular.js, D3, Google and Facebook apis, firebase, offline applications, etc. Also I am founder of Fitlair.com. It's cloud based platform to analyze and forecast progress in olympic sports. Brief summary: • Founder of Fitlair.com (cloud based platform to forecast sport progress) • 3+ years of software development experience • Web-applications development (Ruby on Rails, NodeJS) • Experience with many databases (Mysql, Postgresql) • Rich front-end development (HTML5, jQuery, Backbone.js, EmberJS, CoffeeScript, d3.js) • Experience with many tools and methodologies (Scrum, Git/Github, JIRA, Heroku, deployment) • Knowledges in business analysis, usability and ui design.
