October 2025: Delivered automated CloudFront cache invalidation integrated into the Bitbucket CI/CD pipeline for development and staging deployments in 4Science/dspace-angular. The feature centralizes AWS credentials via environment variables, fetches the target CloudFront distribution, validates identity, and triggers cache invalidations to ensure timely content updates across environments. A stabilizing fix was implemented to improve reliability, with iterative validation commits guiding ongoing improvements. This work reduces manual cache purges, speeds up content delivery, and strengthens release confidence.

September 2025: Delivered key CI/CD improvements and Dev/Staging environment enablement for 4Science/dspace-angular, enhancing deployment reliability and development velocity. Implemented automated environment activation with 1-replica stability and new triggers (turn-on-dev, turn-on-staging), and hardened the pipeline to guard against missing target files and no-change commits. These changes reduce deployment risk, improve reproducibility, and shorten turnaround from feature to production.
