Lot of experience working Ruby on Rails. In the past 5 years, I position myself as consult for startups that need to grow to the next level. I go in and I help refactor the code made usually by junior developers and I help implementing best practices. I particularly help organizing projects that started small and ended up growing way too big. Organizing large projects in Rails might be a challenge, since its default architecture and conventions are thought for small projects. I I can help your wit any question you might have with Rails, how to organize large portions of code (controller, model, helper, etc.), so it does not drive you crazy and that is code that is a pleasure to work with. Also, I can help implementing best practices and procedures for a better and clean coding.

Developed an application for collecting ad selling user information for major. All in the same request. The application was being hit by 1K request per second and it had to return in no more than 100ms. Major website (like New York Times) were implementing our code for selling and buying other users data. We were collecting and processing the data with hadoop and then making the data available in a large memcache cluster. Everythings was running in Amazon web service and the application was fault tolerant.
