Developed and delivered an Address Matching Testing Workflow for the ministryofjustice/analytical-platform-airflow repository, focusing on end-to-end validation of address matching within the analytics platform. The solution involved creating a YAML-based configuration file that defines repository details, tags, compute profiles, maintainers, and metadata to support robust governance and repeatable validation processes. Leveraging CI/CD and testing best practices, the workflow enables reliable training and testing of address matching, thereby improving data quality across analytical pipelines. This work addressed the need for automated, consistent validation in data workflows, contributing to enhanced data governance and operational reliability within the platform’s infrastructure.
