Top SchoolMichael Hamann is a Forschungs- und Entwicklungsingenieur with 18 years of software experience, combining a PhD-era research focus on scalable community-detection algorithms with practical backend engineering at XWiki. He moved from academia at KIT—where he published work on skeleton-based clustering for big and streaming social networks—to applied open-source development, contributing notable backend improvements to XWiki and feature and XML-RPC enhancements to the widely used DokuWiki engine. Known for pragmatic refactors, migration of legacy components, and fixing subtle integration test and mime-type issues, he balances algorithmic rigor with production-grade engineering. Based in Mannheim, Germany, he brings both top academic grades and long-term open-source involvement, often improving developer-facing APIs and usability in mature wiki platforms.
