Michael Barton led engineering for the rcpch/national-paediatric-diabetes-audit repository, delivering robust data management, reporting, and UI features over 18 months. He architected secure, scalable workflows for CSV ingestion, audit-year handling, and patient data validation using Django and Python, integrating asynchronous processing with Celery for large data imports. His work included backend refactoring, test-driven development with Pytest, and deployment automation via Azure CLI and Docker. By modernizing session management, tightening permissions, and enhancing data export/reporting, Michael improved data integrity, reliability, and maintainability. His technical depth is reflected in comprehensive test coverage, resilient error handling, and continuous delivery practices throughout the project.

March 2026 highlights for rcpch/national-paediatric-diabetes-audit: Delivered key feature work, resolved critical data quality issues, and strengthened test reliability to support trusted metrics and faster iteration. The merge functionality was refactored into a dedicated module with a new merge function, moving merging logic to a separate file and removing unused helpers to improve testability and maintainability. Data integrity improvements include robust handling of missing PDU Numbers in CSV uploads, preventing crashes when values are absent. Validation rules were tightened to avoid flagging legitimate changes to diabetes_type, postcode, or GP code as errors, reducing false positives. Eye screen behavior regression was addressed with fixes and a rollback to preserve stable expectations, while tests were stabilized and formatting cleaned up to meet lint rules. Finally, the Outcomes tab was updated to ensure it includes all patients, enhancing completeness of performance metrics across the audit year. The work demonstrates a mix of technical discipline (refactoring, edge-case handling, test stabilization, linting) and business value (more reliable metrics, safer data import, and improved data completeness).
