For 2025-08, delivered significant improvements in data ingestion for local units and testing fidelity in development emails, with a focus on business value and maintainability. Implemented a Local Units Bulk Upload and Status Management feature set in IFRCGo/go-api, enabling CSV-based mass creation/updating, pre-upload deletions of existing records, and data model changes to track validation status, update reasons, bulk upload handling, and externally managed units. Added a migration to map boolean validation flags to new status codes, improving data governance and traceability. Stabilized migrations by rebasing and merging conflicting changes to ensure reliable deployments. Also enhanced Development Email Preview capabilities to reflect realistic test data, including country context and country_id, and refactored unsubscribe link handling to use a dynamic frontend URL for accurate testing. Overall impact: reduces manual data work, accelerates data freshness for local units, improves testing realism for dev notifications, and strengthens data integrity across the API. Technologies/skills demonstrated: CSV-based batch processing, data model migrations, status mapping, migration conflict resolution, dynamic URL handling, and test fixture enhancement.
