I have developed requirements , designed, coded, rolled out into production and maintain, three ruby on rails sites. The first for categorizing, searchiing and displaying, Policies and procedures for a corporation. The second for managing and reporting the cleanup of a Major League Baseball park after each game. It includes equipment, contractors, and employees assigned to each game.
