I am a freelance Android developer from Germany. I started to develop Android apps right when I got my Motorola Milestone. It all started with an app where students at my university could rate and comment on the meals in the cafeteria. A lot of apps followed the success of this first app and I now have a couple of dozen apps in the Play Store (and other app stores) – ranging from some unsuccessful ideas to 1 million+ downloads apps. I am also an organizer of the GTUG Lake Constance and a frequent speaker at Android events.
