Stephen R Pietrowicz

Stephen R. Pietrowicz contributed to several LSST repositories by delivering targeted improvements in data and configuration management. He enhanced author metadata accuracy in lsst/lsst-texmf and lsst/rtn-095, ensuring reliable attribution for downstream analytics through precise YAML and Python updates. In lsst-sqre/phalanx, he migrated ATOODS and MTOODS configurations to a standardized 10.0.0 format, simplifying key structures and reducing integration issues. For lsst-ts/ts_xml, Stephen implemented the WFOODS subsystem for the LSSTCam Wavefront Observatory Operations Data Service, defining new XML-based events and integrating them into the existing architecture. His work demonstrated depth in Python, XML, and full stack development.
