Kristina Spurgin focused on backend development and data conversion in the archivesspace/archivesspace repository, addressing a bug in the MARCXML Authority Converter. She corrected the logic determining the century prefix in the 008 control field to prevent authority record creation dates before 1970, ensuring compliance with archival standards. Using Ruby, she implemented targeted changes that improved the accuracy of date handling and added regression tests to verify the fix and prevent future regressions. Her work demonstrated careful attention to detail in both code and testing, contributing a well-documented and auditable solution that enhanced the reliability of authority record processing.
