The Velocity Consulting website is a Ruby on Rails application.
The application maintains a profile for all current and former members of Velocity Consulting and all of the projects worked on by Velocity.
The application had a primitive project management system built in which was used as a replacement to our (even more primitive) previous system of using spreadsheets. We have since switched to an actual project management tool.
The Velocity Website application is an open source (MIT License) project, with its source available on the Velocity Web GitHub page.
