Work History

October 2025

5 Commits • 4 Features

Oct 1, 2025

October 2025: Delivered data-driven benchmark refinement, automated release notes workflow, targeted codebase cleanup, and digitization parameter updates. These changes improved accuracy, release efficiency, and long-term maintainability across the detector stack.

September 2025

6 Commits • 1 Features

Sep 1, 2025

In September 2025, delivered targeted bug fixes and stability improvements across four repositories (tweag/nixpkgs, eic/epic, eic/detector_benchmarks, eic/EICrecon). Prioritized fixes that unlock reliable builds and CI reliability, clear release notes, and longer-running benchmarks. Key outcomes: improved Python 3.13 compatibility for mplhep tests; robust Boost discovery during Herwig build; CI streamlined by delegating capybara prerequisites to Spack within containers; benchmark configuration simplifications and extended timeouts to avoid premature terminations; and release-notes accuracy by excluding Dependabot authors. Overall impact: reduced time spent on debugging CI/build issues, increased release cadence and reproducibility, and demonstrated cross-repo collaboration and tooling improvements.
