We are a team of two developers, specialising on cross-platform mobile application development with phonegap and backbone.js. We tried different technologies, before settling for this approach. So we also have experience in sencha touch, as3/flex and titanium, if you need help with your existing project. Additionally to mobile app development, we can help you with your backend development as well. We are comfortable working with php webframeworks like symfony or zend, as well as ruby on rails and sinatra. Due to customer agreements we cannot publicly show all of our work, but we can show more work upon request. You can checkout some personal projects here:
