Sam Coy
Worked on the nhsuk/manage-vaccinations-in-schools repository, delivering features and fixes that strengthened data privacy, access control, and operational reliability. Over eight months, implemented end-to-end PII access logging, bulk data management tools, and robust auditing for sensitive operations, using Ruby on Rails, SQL, and JavaScript. Enhanced data integrity through schema migrations, policy enforcement, and test-driven development, while improving UI stability and deployment reliability. Addressed complex requirements such as consent-aware bulk removals, team merging via CLI, and secure access for healthcare assistants. The work demonstrated a methodical approach to backend and frontend development, with a strong emphasis on compliance, traceability, and maintainability.
