Markus Eisele

I help Java teams build AI-ready, cloud-native systems that are fast to change and boring to operate. For more than 20 years I have worked with large enterprises on modernizing Java platforms. From heavy monoliths to Quarkus-based, container-first architectures. Today I focus on how Java, open source, and local AI models come together in real systems, not demos. I am a Java Champion, author, speaker, and developer strategist at IBM. I write the Enterprise Java and Quarkus Substack, The Main Thread, where I publish deep, hands-on tutorials.
