Beamto.us - Rails/Backbone/CoffeeScript development

We are an upcoming startup focusing on underground electronic music. Our current beta can be seen at http://www.beamto.us. It uses Rails/Backbone/Coffeescript/pgsql stack. Going forward, we need to add more features. We are expecting to have around 5-10 hours of work with budget of 10-15/hr with 15 being a stretch. Please send me your Github ID so that I can see some of you previous work or something. The task will require working on both Ruby and Backbone side but lot of things are already based on framework so we can just follow that syntax. I will assign you issues on Github and we can discuss how much time it will take and go from there. If you are interested, please message with the final hourly rate that you can work upon and we will go from there. Bonus point, if you have experience with writing tested code.
