“Christoph has a very high bar for code quality and demonstrates this by implementing clean and comprehensible design patterns and architecture. He can break down complex projects into smaller concise milestones and consistently deliver upon those timelines. I would certainly work with Christoph again and trust him to spearhead any iOS project.”
