Alexander Tiekoetter developed and integrated the ALICE3 Data Quality (DQ) data model and analysis workflows for the AliceO2Group/O2Physics repository. His work established new data structures and automated workflows in C++ to enable data quality checks and efficiency calculations, supporting the broader ALICE3 DQ integration. By focusing on data modeling and algorithm design, Alexander delivered a targeted, single-commit implementation that improved data quality visibility and reproducibility of QA signals. This foundation streamlines future deployment of ALICE3 DQ features and enhances the data-to-physics pipeline, demonstrating strong skills in C++, data analysis, and workflow automation within a collaborative software environment.
