Built out user facing features for both the web and desktop versions of Paper

Modified the entire ads publisher stack to create a diagnostic tool for Ad Exchange, Google’s exchange bidding software. This involved defining new entities to store diagnostic information, querying databases and stats tables to get up to date data, adding to an existing ads service, and finally rendering the diagnostic data in the form of a pie chart on a new Diagnostic tab on the DoubleClick for Publisher website.

The diagnostic tool was written in Java and Dart with the Angular2 framework, and tested using unit and end to end tests.
