Dr. Dominik Hauser is an iOS developer working for a small company in western Germany. In over 11 years as an iOS developer, he has worked on many different apps, both large and small. In his spare time, Dominik builds small (often silly) apps and explores how he can become a better iOS developer. He talks at conferences, writes books, and is active in the iOS community in general. His most successful open source component (in terms of stars) is a pull-to-refresh control for a table view that consists of an actual SpriteKit game. Before Dominik became an iOS developer, he was a physicist, researching the most powerful photon sources within our galaxy.
