October 2025: Delivered a comprehensive permissions and authentication upgrade for NHSDigital/dtos-manage-breast-screening. Key features include a revamped Authentication URL flow with persona/role integration and provider context; alignment of the permission model for critical workflows (notably PERFORM_MAMMOGRAM_APPOINTMENT); and provider/model enhancements to streamline data access. Major bug/quality work included updating test fixtures to include roles, removing unnecessary checks, cleaning provider role references, and removing legacy Django Admin UI. Security improvements were implemented with a custom CIS2 authentication backend and unusable passwords for new User records. Local development and build reliability were strengthened via config-driven local setup, added personas/demo data, Node/Docker updates, linting for model usage, and Makefile/workflow refinements. Impact: tighter security, clearer, role-based access controls, more reliable tests, faster onboarding for local development, and a cleaner, more maintainable codebase. Skills demonstrated include Django/Python development, role-based access control, security hardening, containerization with Docker, modern Makefile workflows, and test-driven development.
