Worked on enhancing data processing pipelines for the DUNE project, focusing on performance optimization and data compatibility. In the duneopdet repository, replaced the Signal() method with SignalROI() in the Op Hit Finder, which improved waveform processing speed by reducing data access latency. In the waffles repository, extended the HDF5 reader to support multiple detector types by introducing a detector parameter and updating mapping logic, thereby increasing data interoperability across configurations. Utilized C++ and Python, applying skills in configuration management, data engineering, and signal processing to deliver two new features that enable faster analysis cycles and broader detector support.
