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 that determines the century prefix in the 008 control field, ensuring authority record creation dates cannot be set before 1970. This fix involved careful analysis of MARCXML data structures and Ruby code, with additional regression tests implemented to verify correct handling of edge cases. Her work emphasized robust testing and traceable commits, contributing to more reliable authority record management. Kristina’s efforts demonstrated depth in Ruby programming, backend systems, and automated testing within archival data workflows.
