During March 2026, contributed to open-ani/animeko by enhancing Gradle build performance through the introduction of a gradle-daemon-jvm.properties configuration and updating setup documentation, which streamlined local build times and improved developer onboarding. In parallel, addressed a stability issue in openjdk/leyden by fixing a Linux jpackage launcher crash that occurred when processing large numbers of JAR files, implementing robust read and write data transfer in C to prevent segmentation faults. These efforts demonstrated practical expertise in build automation, Linux development, and system programming, resulting in faster builds, reduced packaging risk, and more reliable multi-JAR processing for both projects.
