Sophia Sun developed robust data pipelines and backend features for the CCRI-POPROX/poprox-storage and CCRI-POPROX/poprox-recommender repositories, focusing on scalable data export, analytics readiness, and schema evolution. She engineered pandas-based export flows to AWS S3 in Parquet format, implemented database migrations with Alembic and SQLAlchemy, and enhanced recommender test data generation. Her work included refining export schemas for analytics, improving migration reliability, and adding telemetry for experimental tracking. By addressing data quality, maintainability, and operational efficiency, Sophia delivered solutions that improved downstream processing, enabled richer analytics, and ensured safe, auditable changes across evolving backend and data engineering requirements.

In January 2026, CCRI-POPROX/poprox-storage delivered two feature enhancements that strengthen fundraising operations and reporting. The Charitable Donation Options Update and Migration implemented a targeted migration to Feeding America, backed by a new migration script and updated migration guidance in the README, enabling safer account-level updates and smoother production rollout. The Compensation Export Enhancement added per-account survey counts to the export, enabling more accurate analytics and reporting for funding decisions. Overall, these deliverables improve data integrity, visibility for stakeholders, and operational efficiency. No critical bugs were reported for this period; the engineering focus was on reliable migrations, clean documentation, and enhanced analytics capabilities.
