Hello,
I have years experience in Ruby on Rails web applications. I've worked on enterprise level applications in Rails 4/3.2 and have experience dealing with Ruby 1.8, 1.9, and 2.0. So whichever versions you're most comfortable using for your project I can work with. I can deliver you a solid prototype with functional and unit tests within a week for a project of this caliber. Also, I work from California so I'm on west coast time if you ever need to contact me about the project. Look forward to working with you,
Josh H-
