I’m Christian Grobmeier — Open Source Developer, Author, and long-time contributor to the Apache Software Foundation, where I currently serve as VP of Data Privacy and on several project management committees. As a Java Champion, I write, teach, and maintain projects that keep systems reliable and communities connected.
I currently operate Time & Bill and offer professional services with my company Grobmeier Solutions GmbH.
In early 2025, I joined the first cohort of the GitHub Secure Open Source Fund, helping strengthen the security of Apache Log4j and related open-source projects. My reflections on open source, resilience, and engineering culture live at Logging Off.
