Joe Dods worked on the ministryofjustice/analytical-platform-airflow repository, focusing on improving the reliability of ETL workflows by addressing a scheduling issue in an Airflow DAG. He updated the DAG’s start and end dates to ensure workflow runs aligned with business hours, directly impacting the timeliness of downstream analytics. To maintain compatibility and stability, Joe upgraded the deployment process by bumping the Docker image tag, leveraging CI/CD best practices. Using Python and YAML, he ensured all changes were version-controlled and traceable to a specific commit, enabling rapid rollback and auditability. The work demonstrated depth in workflow management and deployment automation.
