My only experience is of two years, as an intern, at College, where I had the opportunity to build projects using Ruby On Rails and Android. There, I was able to participate in many projects including the main project of the University which is its app https://play.google.com/store/apps/details?id=br.unifor.mobile. The RoR's projects were for client's company internal use, so I will not be able to present. But I had the chance to participate in 3 RoR's projects.
