I am a freelance developer. I primarily develop Ruby on Rails/ JavaScript Web Applications. I think Ruby on Rails is the best framework to develop web applications, as it makes possible to develop great applications faster. I have worked with Rails 2.x and Rails 3 applications. I have worked with pure JavaScript, jQuery, Prototype JS JavaScript frameworks/ libraries. I like to create really great applications, which also makes me a better developer.

I follow Test Driven Development religiously, because it makes it possible to develop a robust application and makes the whole development and post-development an enjoyable experience, which would create a great environment for me and also importantly for my customers. I use RSpec mainly for testing my applications. I love developing Ruby on Rails/ JavaScript Applications. I have experience developing two functionality filled websites in Ruby on Rails. Both the websites functionality like rating, badges, forums, link submissions and social features. I had used jQuery, Backbone.js, Prototype.JS libraries while developing those applications.
