In April 2025, Olga Filippova focused on enhancing data quality and standardization within the NYCPlanning/data-engineering repository. She addressed inconsistencies in CEQR seed data by aligning chapter names with the NYC 2021 Technical Manual, specifically updating entries in analysis_framework, land_use, and community_facilities. Using her expertise in configuration management and data seeding, Olga worked primarily with CSV files to ensure semantic consistency across datasets. This targeted bug fix improved downstream analytics reliability and auditability, supporting future onboarding and standardization efforts. Her work demonstrated a methodical approach to seed data management and effective use of version control in a collaborative environment.
