Wooyoung Jang engineered and maintained the build and release infrastructure for the DUNE software stack, focusing on cross-repository dependency alignment and version management across projects such as DUNE/dunecore, duneopdet, and dunereco. He systematically upgraded C++ and CMake-based build systems, ensuring compatibility with evolving dependencies like larsoft and improving reproducibility and stability for downstream users. His work included targeted bug fixes, compiler compatibility improvements, and the integration of new utility modules, all while coordinating synchronized versioning and packaging across seven repositories. This disciplined approach reduced technical debt, streamlined release cycles, and enhanced maintainability for complex simulation software environments.

February 2026 performance summary: Led a cross-repo dependency and version upgrade initiative across seven DUNE repositories (DUNE/dunesw, DUNE/duneopdet, DUNE/dunereco, DUNE/dunecore, DUNE/duneana, DUNE/dunesim, DUNE/duneprototypes) to align versions and dependencies for improved compatibility and faster feature adoption. Actions included updating dependencies to latest compatible versions, validating build stability, and ensuring consistency of versioning across environments. A targeted bug fix in Dunereco aligned DuneCore and DunePrototypes version strings with updated dependencies, eliminating environment drift and simplifying release cycles. The consolidated effort enhances cross-environment compatibility, reduces environment-related failures, and accelerates access to new capabilities for downstream workloads.

Concise monthly summary for 2025-12 focusing on business value and technical achievements across the DUNE software stack. All repositories underwent system-wide dependency and version upgrades to align with larsoft v10_15_00 and to enable access to the latest features and fixes. Notable fixes were applied to critical modules to maintain compatibility and stability by adding required utility headers and necessary ROOT dependencies. These changes improve build stability, integration readiness, and future maintainability across the DUNE projects.

October 2025 performance summary focused on release engineering and dependency hygiene across the DUNE software stack. Delivered consolidated release readiness through version bumps and dependency synchronization across seven repositories (duneana, duneopdet, dunecore, dunereco, dunesim, duneprototypes, dunesw) to align with the v10.x release line. Updated CMakeLists.txt and ups/product_deps to reflect new version strings and dependency references, enabling consistent builds, packaging, and release packaging. These changes reduce integration risk, improve build reliability, and accelerate time-to-release by ensuring all major components are aligned to the same baseline.
