This Site
This site has been designed from scratch by the Web Development team at Ultimate One. The main application runs on Rails. The team chose Rails as being a full-stack MVC web framework it is capable of producing high-quality, structured, great looking web applications.
Shane Zadrozny said, "We wanted a Web Application with a database back end that we could maintain and extend. It had to be compatible with team development and be capable of supporting some of the latest Web 2.0 technologies such as AJAX."
Naturally being a company offering Website Design and Maintenance as one of its portfolio of business services, Ultimate One had to really push the boundaries on its own website.
