PROFILE
Adam Brousseau
Adam Brousseau engineered robust build and CI/CD infrastructure for the eclipse-openj9/openj9 repository, focusing on reliability, maintainability, and cross-platform consistency. He modernized Docker-based build environments by diversifying image sources, migrating container registries, and introducing dynamic tagging to reduce outages and maintenance overhead. Adam enhanced Jenkins pipelines by separating environment setup from source retrieval, improving log clarity and bottleneck analysis. He upgraded AIX PowerPC 64-bit builds to JDK 24, aligning with evolving platform requirements. Leveraging Groovy, YAML, and Shell scripting, Adam’s work demonstrated depth in build engineering, DevOps, and configuration management, resulting in more stable, auditable, and predictable builds.

Aug 1, 2025For August 2025, delivered CI/CD Build Environment Modernization for eclipse-openj9/openj9, focusing on reliability, clarity, and cross-architecture consistency. Core changes include migrating the container registry to ghcr.io, ensuring CUDA image builds use the latest base images with differentiated tags, and updating the boot JDK to Semeru 24 for Java builds. These improvements reduce build drift, simplify maintenance, and improve deployment confidence across all architectures, contributing to faster release cycles and more predictable builds.

Jul 1, 2025July 2025 — eclipse-openj9/openj9: Delivered an upgrade of the AIX PowerPC 64-bit Build Environment to JDK 24 (build 123). Updated defaults.yml to switch AIX PowerPC 64-bit builds to the newer bootjdk, aligning with the latest platform compatibility and performance improvements. No major bugs fixed this month. Overall impact: stronger platform support for AIX, more stable CI/builds, and a clear upgrade path for future JDK updates. Technologies/skills demonstrated: build tooling, release engineering, platform-specific upgrade processes, JDK bootstrapping, and YAML-based configuration management.
