Chris Müller is a pragmatic software developer with 12 years of experience based in the Cologne-Bonn region, currently building products at Peakwork AG. He brings a strong backend focus and a meticulous eye for documentation and security, demonstrated by sustained contributions to the TYPO3 CMS core and its official documentation where he clarified APIs, fixed vulnerabilities, and improved TypoScript references. His background in AI and robotics from Universität Bremen and hands-on research roles at DFKI and Fraunhofer give him a systems-oriented mindset and comfort with complex technical domains. Equally comfortable shipping code and improving developer-facing docs, he’s the kind of engineer who reduces friction for both users and fellow developers through clear explanations and thoughtful fixes.
