Ruby on Rails Developer

Poland - Tests: 5 - Portfolio: 7

I have been a Ruby on Rails programmer for almost 5 years now (since early 2010). I have worked with various Polish companies, including micro-teams and a Corporation. I focus mainly on back-end development, such as json based APIs and try to master the techniques of BDD. I am happy whenever I can break out of Rails` default presentation schemes, and complement its backend with a completely new presentation-oriented technology, like Backbone.js. Outside of Ruby I am interested in learning Python and (very recently) C. I have experience as both a team player and a self-sufficient developer. I always try to pursue the best solution and am keen on learning new technologies, especially when I can put them to practical use.

Sergey K.

Ruby on Rails Developer/Consultant

Russia - Tests: 2

Looking for a dev to join your team, do a code review or start a new project from the ground up? Look no further! I have extensive experience in creating and maintaining applications of all sizes. (From simple proof of concepts and MVP's to complex SAAS platforms). I follow best practices and latest developments in ruby/rails world, know most design patterns and anti-patterns and can use agile practices (TDD/BDD/CI) effectively. I'm used to work in a well organized environment (with github, fetures in separate branches, pull requests, code reviews, CI, staging and QA) and can help you set one up, or I can adapt to whatever process you use just as well. On top of that I've been working remotely for the last 6 years, so I understand importance of communication and very used to doing everything without hand-holding and micromanagement. Give me a task, I'll ask for clarifications if something is not clear and then I'll get it done as fast as possible while maintaining code quality. A bit of technical stuff: Over the years I've dealt with pretty much everything related to development of web applications. Ruby 1.x, 2.x Rails 3 and 4 (including migrations from 3 to 4): file storage (AWS/Google) and file processing, SQL (postgres, mysql), authorization and authentication (Devise, Cancancan), payment services (Stripe), background processing, scheduled jobs, internationalization and timezones, complex mailing systems, caching and performance optimization, rack middleware and rake tasks, interactions with all sorts of APIs (Google, Adwords, Facebook, Twitter, Rets, and 10+ others) and all kinds of testing (functional, performance, feature and even a/b). I also know front-end quite well (JS/CoffeeScript/jQuery&plugins/React, Bootstrap/ZurbFoundation, Haml/Slim/Saas) and know my way around unix systems (can configure and deploy apps if needed). A very simple app to show you an example of my code:
