Your needs are exactly the things that I know I can help with. I have completed and deployed multiple rails projects, and recently a project management application built with AngularJS on the frontend. I have used Redis and Hstore on Postgresql and would love to dive into MongoDB.
I know that there are many great developers, but I genuinely believe that my personality, work ethic, and drive to improve, will make a great contribution to your team. I have been a developer on projects for Intuit, Lytro, and Curious where I had the great experience to work in a very skilled, cross-functional team. I am new to freelancing so I have an immense desire to build my relationships and skills while working on projects that use tools I enjoy.
I hope to hear from you, and thank you for your time.
