Worked on strengthening the metadata extraction path for the immich-app/immich repository, focusing on backend stability and data integrity. Addressed a critical bug by implementing robust validation checks in TypeScript to prevent server crashes when corrupted assets are encountered during ingestion. Enhanced the backend by introducing constants for PostgreSQL integer limits and enforcing these constraints through improved data validation, reducing the risk of invalid data entering the system. This work increased the overall robustness of the ingestion pipeline, minimized downtime, and reduced support incidents. The approach demonstrated careful attention to backend reliability and data validation using TypeScript and PostgreSQL.
