I build open-source Android apps and libraries under the 2312 development name, such as RateBeer and Transdroid. They go back to 2009 and nowadays have 100s of thousands of active users. I love raising the bar of my graphical UI and UX designs and utilizing the Android platform to its fullest extent. Recently I have fallen in love with RxJava.
Since 2013 I have also developed Android apps and libraries professionally. I am currently responsible for the Android version of our iBeacon advertising platform SDK, integrated into multi-million user Android apps, and jointly lead our R&D efforts translating innovative ideas into real technology. I am especially proud of my big brand apps with millions of users and our beacon-based indoor positioning system.
