PROFILE

Andrew Olivier

Andrew led coordinated release engineering across the DUNE software stack, delivering versioned, dependency-aligned builds for repositories such as dunecore, dunesw, and duneopdet. He implemented CMake-based version control and ups/product_deps management to ensure reproducible builds and streamlined downstream deployment. Using C++ and Python, Andrew automated batch job submission and grid computing workflows, notably in EMPHATICSoft, enabling scalable Monte Carlo production. His work included refactoring build scripts, resolving Clang compatibility issues, and integrating LArSoft upgrades for forward compatibility. The depth of his contributions established robust release discipline, improved CI reliability, and reduced integration risk across complex, multi-repository scientific software environments.

Work History

May 2025

15 Commits • 7 Features

May 1, 2025

May 2025 focused on release readiness and dependency alignment for the 10.06 series. Delivered coordinated version bumps and dependency updates across seven DUNE repositories, establishing a stable baseline for downstream builds and deployments. Key outcomes include updated dependencies to 10_06.00, patch increments to 10.06.00d01, and consistent changes in CMakeLists.txt and ups/product_deps to support reproducible builds and streamlined deployment.

April 2025

10 Commits • 7 Features

Apr 1, 2025

April 2025 focused on delivering a coordinated release cycle across the DUNE software stack, establishing the v10_05_00d00 baseline and upgrading core dependencies to improve stability and feature access. Seven repositories were updated in lockstep to align versioning and build metadata, preparing the suite for downstream validation and production use. Note: no explicit bug fixes were performed; changes target stability, compatibility, and release readiness through dependency and versioning optimizations.

Mar 1, 2025

March 2025 release engineering across seven DUNE repositories (dunecore, duneopdet, dunesim, dunereco, duneprototypes, dunesw, duneana). Delivered the 10.04.x release series by applying a coordinated sequence of version bumps from 10.04.04d00 through 10.04.07d01 in CMakeLists.txt and ups/product_deps. This work ensures a consistent release state for the 2025-03 cycle and improves downstream dependency tracking and rebuild reproducibility. No major bug fixes were reported; focus was on release readiness and cross-repo alignment. Overall impact includes reduced integration risk, better traceability of changes, and smoother patch availability for downstream users. Technologies demonstrated include CMake-based versioning, ups/product_deps management, release engineering discipline, and multi-repo coordination.

February 2025

Feb 1, 2025

February 2025 monthly summary: Focused on stabilizing the DUNE software stack for the 10.04.x release by aligning dependencies, updating interfaces for LArSoft v10, and consolidating release tooling across multiple repos. Delivered forward-compatibility with WireReadout interface in ROIAna/ROIProd, fixed critical Clang build issues, and completed a cohesive 10.04.x patch-series rollout across the DUNE stack. This work reduces build failures, improves packaging consistency, and accelerates downstream deployment and maintenance.

January 2025

30 Commits • 9 Features

Jan 1, 2025

January 2025 release cycle across the DUNE suite focused on release engineering, versioning discipline, and dependency alignment. Delivered coordinated maintenance and patch releases across dunesw, duneopdet, duneprototypes, dunesim, duneana, dunereco, and dunecore, standardizing release versions to 10.03.01d02 (and transitioning from 10.02.02d01 where applicable). Consolidated multiple commits into single release updates per repo, improving traceability and reducing version drift. This work enables reproducible builds, stable downstream packaging, and smoother hotfix workflows across the ecosystem.

December 2024

Dec 1, 2024

December 2024 performance summary for EMPHATICSoft and DUNE repositories. Delivered end-to-end grid-enabled Monte Carlo workflows in EMPHATICSoft and coordinated release/versioning across the DUNE stack, strengthening production readiness, CI reliability, and release traceability.

November 2024

44 Commits • 9 Features

Nov 1, 2024

November 2024 monthly summary focusing on release engineering, dependency upgrades, and build reliability across DUNE project repositories. Key features delivered include systematic LArSoft upgrades, release version bumps across the 10.01.x series, and TensorFlow isolation to improve Clang compatibility. Major bugs fixed include clang-related build warnings and stability improvements in build scripts. The work established a stronger release discipline, improved cross-repo consistency, and laid groundwork for a robust 10.01.x deployment.

October 2024

18 Commits • 7 Features

Oct 1, 2024

October 2024 monthly summary: Executed a coordinated patch-release cycle across the DUNE codebase focused on stability, packaging, and dependency alignment. Implemented targeted fixes for v10 geometry compatibility and improved build/test reliability, and advanced data packaging readiness for distribution. Delivered consistent versioning across seven repositories, enabling smoother downstream deployment and integration.
