PROFILE
Alistair White-horne
Alistair Whitehorne developed and maintained core immunisation data and workflow features for the nhsuk/manage-vaccinations-in-schools repository, focusing on data integrity, privacy, and operational reliability. He engineered robust backend systems in Ruby and Ruby on Rails, integrating FHIR standards and API-driven data flows to support vaccination record management, consent handling, and secure data exports. His work included CLI tooling, feature-flagged rollouts, and UI enhancements, with comprehensive test coverage and code refactoring to ensure maintainability. By implementing data validation, import logic, and privacy controls, Alistair delivered scalable solutions that improved data quality, reduced manual intervention, and enabled safer, auditable healthcare operations.

Jun 1, 2025June 2025 monthly summary for nhsuk/manage-vaccinations-in-schools: Implemented Cohort Import Progress Bar for mavis generate cohort-imports to provide real-time feedback during long-running import processes. The progress bar initializes with the total patient count and increments after each patient processed, improving UX during large imports and reducing uncertainty for operators. This work is linked to commit a7a5abfd752d4de1f9bffea5642ce7c977695517 for traceability. Overall impact: smoother user experience for large data imports, better visibility into import progress, and clearer assurance during batch operations. No major bugs reported this month. Key business value includes reduced manual monitoring effort and more predictable import times. Skills demonstrated: CLI UX enhancement, progress-tracking logic, and commit-based traceability.

Mar 1, 2025March 2025 monthly summary for nhsuk/manage-vaccinations-in-schools: Implemented privacy-focused enhancement in the CarePlus data export pipeline by redacting restricted patient addresses. The change ensures restricted patients have an empty address in exported data, aligning with the existing programme_vaccinations_exporter.rb behavior and strengthening privacy controls. Delivered in the nhsuk/manage-vaccinations-in-schools repository with a clear, auditable commit. This reduces exposure risk and supports regulatory compliance for patient data.
