Janina Hakenmuller focused on configuration management and data processing optimization within the DUNE/dunesw and DUNE/dunereco repositories, delivering two targeted features over one month. She improved data processing efficiency by modifying FCL configuration files to exclude deconvolved optical waveform data, reducing file sizes and enhancing storage and processing performance. In DUNE/dunereco, Janina clarified and aligned PointResTree configurations with the Marley generator, introducing clearer naming conventions and adding a NuEScatter 1x2x2 configuration to support geometry-based analysis. Her work demonstrated depth in configuration management and data processing configuration, addressing specific workflow needs without introducing bug fixes during the period.
