Apart from being an iOS developer, I enjoy most of my time exploring. In the winter, I have fun playing board games or any games with friends, expand my music and book library, and have the occasional nature hike. During the warmer months, I enjoy sailing for sport, either in the rivers of Berlin or on the coasts of Baltic and North Sea, mountain trekking, nature hikes and visiting new places.

When forced indoors, I follow a number of sci-fi shows, I read books on various subjects, and I spend a large amount of my free time exploring the latest iOS design and development features.
