Drew Heles worked on deployment and integration features for the DSpace/DSpace and DSpace/dspace-angular repositories, focusing on configuration management and containerization. He aligned Docker deployment configurations for the 8.x release, standardizing Dockerfiles and docker-compose files to ensure consistent versioning and reproducible environments across both repositories. Using Docker, YAML, and DevOps practices, Drew improved CI/CD reliability and reduced deployment errors between development, staging, and production. Additionally, he delivered DataCite sandbox URL support in the DSpace/DSpace crosswalk configuration, enabling API testing and data integration via XSLT. His work demonstrated technical depth in release engineering and environment standardization.
