The devs are hardcore Java/Javascript. The have perused NXT because that is one of the coins we would like to integrate with depending on the community view.
We are also going to have libraries available so that other coins can integrate our coin.

We have integrated Localization, Gradle, Continuous Integration (http://jenkins-ci.org/) with a very modular approach so that multiple developers can work on the base with little to no refactoring like some other projects. The architecture was my main focus for the app.
