  Novacom

  Architecture, implementation and design development for the new implementation of a large existing application. One main concern was the documentation of the frontend in form of a living styleguide enabling backend developers to use it without any further knowledge of HTML or CSS. The frontend components had to be completely configurable by a HTML-API. The best comparision would be that I developed something similar to a company tailored Twitter Bootstrap. The browser support had to involve the IE8. Furthermore I developed Backbone.js components, custom jQuery-Plugins and a mobile Ember.js app.
