Worked on the nationalarchives/ds-infrastructure-web repository to implement an Enrichment Timing Feature Toggle, introducing the ENRICHMENT_TIMING_ENABLED configuration flag to control timing enrichment across different environments. The approach focused on configuration management and system administration, using JSON to define and manage the new flag. Staging environments were configured to keep the feature disabled by default, supporting safe testing and performance profiling before broader rollout. This work established a foundation for controlled feature releases, observability, and rollback strategies, ensuring environment parity and traceability through targeted commits. The implementation emphasized maintainability and operational safety in managing feature deployment across the application lifecycle.
