PROFILE
Joe Dekoning
Joe Dekoning focused on build engineering and CI/CD modernization for the eclipse-openj9/openj9 and openj9-omr repositories. He upgraded the Linux 390 build system by updating the compiler to v13.2 and aligning configuration files to ensure consistent, stable builds across variants, using XML and YAML for build system configuration. On the Windows side, Joe modernized the CI pipeline by upgrading the Azure client image to Windows 2022/2025 and updating the environment to Visual Studio 2022 and the latest Windows SDK. His work reduced environment drift, improved pipeline reliability, and supported ongoing product lifecycles through disciplined DevOps practices.
