Just completed an internship with a DOJ contractor. It was a fun way to work on a Ruby on Rails application. They were using an internal tracking application to log calls and e-mails. The features I added to the tracking application were:
- search call and e-mail log ( just used ActiveRecord, since it was an internal application)
- sortable tabular data using jQuery
- display statistics about calls/e-mails over time
- line graphs
- pie charts
- maps
