Andreas Molander contributed to several core ALICE O2 repositories, focusing on detector simulation, quality control, and code governance. He enhanced geometry alignment macros in AliceO2Group/AliceO2, enabling precise misalignment creation and automated validation using C++ and ROOT. In AliceO2Group/QualityControl, Andreas developed automated MIP peak monitoring for the FT0 detector, integrating Gaussian fitting and histogram analysis to streamline calibration workflows. He also updated Monte Carlo digitizer configurations in AliceO2Group/O2DPG, aligning simulation parameters with 2024 run conditions. Throughout, Andreas managed CODEOWNERS files across multiple repositories, improving review accountability and process consistency using Git and YAML.

June 2025 — AliceO2Group/O2DPG: Implemented Monte Carlo digitizer configuration update for FIT aligned to the 2024 run period. Adjusted ADC channels per MIP for FT0 and FV0 based on run-number ranges. The changes are temporary until CCDB configurations are available. Documentation and commit tracing prepared to support CCDB migration and future audits. Impact: improved MC realism for 2024 data and a clean path to CCDB integration.
