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 and Kotlin.
Since 2013 I have also developed Android apps and libraries professionally. The first years I have developed big brand apps with millions of users as well as an iBeacon advertising platform SDK with indoor positioning system. I currently work as a contractor at KBC Belgium. Our team and app has grown significantly, and I support this through renewal of our tools, making proof of concepts and giving tech talks for my collegues.
