Danny Preussler

Danny is a mobile developer by heart. He lives and works in Berlin, the city he loves as much as Android.

Danny signed the Software Craftsmanship manifesto as a strong believer in the value of lifelong learning. He dreams in clean code and could speak about unit testing all night. That's also his favorite topic when speaking or writing about Android.

Danny was in charge for Android for eBay's classified business in Germany before moving to Groupon to build a team there bringing mobile to the lives of merchants. Even before Android came along he programmed for mobile phones and every device that could run some kind of Java.

Danny is a Google Developer Expert for Android and Kotlin.
