👤
Senior🎓
Top SchoolKai Hartwig is a DevSecOps advisor and founder with over a decade of hands-on experience building and operating resilient web and CMS platforms for established companies. He combines pragmatic engineering—programming, log analysis, and pipeline construction—with strategic design to prevent costly architecture mistakes before they happen. As CEO of Moselwal he runs continuous automated operations for 100+ production CMS instances, keeping systems secure, up-to-date and maintenance-free for clients. He limits advisory work to a few high-impact engagements monthly, focusing on DevSecOps, CI/CD, mTLS and secure architectures where decisions have real consequences. Based in Düsseldorf, he balances technical leadership with on-the-ground execution and even finds time to be a winemaker outside of work.
