Apart from having built my project's site, which was not a great deal, I'm working on an automation system on Rails 3.1 with a MySQL backend. I've also set up Redis as cache, but I'm planning to use it as a secondary storage as well. This BPA system integrates with Google AdWords API to report statistics about ad campaigns (reporting is one of the app's primary functions), as well as APIs provided by our local Russian ad gateways. Front-end is on jQuery and SCSS. In my university years I've been working on a task tracking system on Rails 2.0 with Prototype, but I eventually abandoned it, not having enough free time.
