WIN (Web Information Network) Replacement project
a java web application used to record and analyse intelligence data about crimes received from British Transport Police, Bus garages and Schools. The original WIN application was developed seven years ago by a third party company who held the intellectual property rights, so TfL decided it was more cost effective to rewrite the application in-house to incorporate new customer requirements.

- Technologies used: Java 6, JSPs/Serlvets, Spring 3.*, Spring MVC, Spring Webflow, JSPTabControl Library, DWR Ajax, JQuery, Hibernate, PL/SQL, Oracle 10g
- Unit testing with JUnit/Mockitos
- Build with Ant, and deploy to OC4J dev and test environments
