Kostas Tsiounis developed a cross-platform OpenSSL bundling solution for the eclipse-openj9/openj9 repository, focusing on build engineering and CI/CD processes. He standardized the inclusion of the openssl_bundle dependency across multiple architectures, including ppc64le_linux, s390x_linux, ppc64_aix, x86_64_linux, and aarch64_linux, using YAML to manage build configurations. This work addressed inconsistencies in security and dependency management, ensuring that all supported platforms benefit from uniform OpenSSL handling. By capturing the change in a single commit, Kostas improved build reliability and CI throughput, enabling more consistent multi-architecture builds and supporting faster, more dependable release cycles for the project.
