Simon contributed deeply to the rcpch/national-paediatric-diabetes-audit repository, building robust data pipelines, audit workflows, and analytics features for national paediatric diabetes reporting. He engineered cross-year dataset compatibility, audit-period validation, and granular access controls, using Python, Django, and Pandas to ensure data integrity and governance. Simon refactored CSV ingestion and validation logic, optimized KPI calculations for performance, and enhanced patient reporting with advanced filtering and visualization. His work included scalable UI improvements, comprehensive test coverage, and CI/CD reliability upgrades. By integrating geospatial analysis and refining user management, Simon delivered maintainable, business-critical solutions that improved audit accuracy and stakeholder confidence.
April 2026 performance: Delivered a comprehensive refactor and feature set for the national-paediatric-diabetes-audit repository, focused on cross-year dataset compatibility, data integrity, and scalable UI controls. Consolidated CSV heading/dtype/year handling into a single ALL_HEADINGS structure with derived ALL_DATES and ALL_VISIT_DATES, enabling consistent processing across 2021 and 2026 datasets and restoring dataset_year handling in forms. Implemented dataset_year awareness in CSV upload and coalescing logic, added CLI support (--dataset_year) and tests to guard against cross-year header mismatches. Introduced viewing_stale_data for uploading previous-year submissions and a UI improvement to support multi-employer PDUs with a dedicated dropdown and permission-aware banners. Reworked KPI logic to count directly in the patient-report view instead of via a KPI class, significantly reducing database queries and improving page load times. Expanded cross-year testing (2021 vs 2026) with extensive TDD coverage for treatment, smoking, and HbA1c outcomes, plus updated documentation (Agents.md and field mappings).

September 2025: Delivered two contributing features for the rcpch/national-paediatric-diabetes-audit repository that improve triage efficiency and data presentation. The Prioritized Patient Report Ordering Based on Health Status reorders the patient report list to surface incomplete or failed health checks first, enabling faster attention to at-risk cases. Excel Report Formatting Improvements add automatic column width adjustment and date-only formatting in exports to improve readability and reduce confusion. No major bugs fixed this month. These changes deliver tangible business value by accelerating decision-making, enhancing data quality, and improving stakeholder reporting for quality assurance and regulatory compliance.
