Cristian Schuszter at JavaOne 2026

Jim Grisanzio from Oracle Java Developer Relations talks with Cristian Schuszter at JavaOne 2026. Cristian is a PhD in systems engineering and a Tech Lead at CERN in Geneva. He's been at CERN for 8 years, but he's been coding since he was eight years old. He loves working with and contributing to the Java community and other Open Source projects. This was Cristian's first JavaOne, and his session, "30 Years of Java Development: Keeping it All Together," covered how CERN keeps Java running across teams since 1998. Like any large company, CERN uses a lot of legacy code supporting systems that, in Cristian's words, "need to keep running." Java is not only used for business critical applications at CERN but also for accelerator system operations. On working at CERN among Nobel laureates, Cristian said, "I felt like I thrived in this kind of environment." Cristian also helped revive the Voxxed Days developer conference at CERN and started the CERN Java User Group.
