As a professional software developer, It's a proud to work for the great project like you posted.
I'm an expert of Ruby On Rails for back end, and HTML5,CSS and JQuery for front end job.
I've delivered many web sites(integrating Google Api like Geocoding) which works well still now and my clients are all satisfied with my work,quality,ability to launch product on time and great after service work.
With my skills and history, I can deliver you exactly what you need before deadline.
As a full-time freelancer, I'm ready to start work RIGHT AWAY.
Your requirements need long time work, so keeping in touch with client is very important for making a product exactly what a client needs.

Working with me would be fun.
I hope we can work together for mutual benefits and prosperity.
