Worked on the ministryofjustice/analytical-platform-airflow repository to deliver MDSS Data Interval Slicing in Airflow, enabling per-run data slices for incremental data processing. Leveraged Airflow and YAML to introduce DATA_INTERVAL_START and DATA_INTERVAL_END template variables, allowing workflows to load data by interval and improving data accuracy. Enhanced deployment safety by implementing a Docker image security update and a minor version bump, supporting interval testing and reducing deployment risk. Focused on configuration management and CI/CD practices, the work reduced data latency and streamlined workflow execution. The engineering approach emphasized maintainability and reliability, addressing both data processing needs and operational security requirements.
