When teaching introductory programming in Java to his students, Hans brags about his hometown in Indonesia. Sharing little knowledge of geography about Indonesia with his students helps them discover that Java is also the name of an island where their instructor was born. A scholarship awarded by the Indonesian government allows him to pursue his graduate degrees at Michigan State University. As a scholarship awardee, he was required to return and work for the Indonesian government after finishing his doctoral degree. After completing the employment requirement as a university professor in Indonesia, he decided to come back to teach in the US and chose West Michigan as the home for his family.
Hans' interest in Android programming began since Cupcake and he continues to stay up-to-date with the latest release.
Having research interests both in mobile applications and computer graphics has motivated him to learn Vulkan mobile-first, by exploring the library using Android NDK.
