Over ten months, Orca UK developed and maintained core features for NHSDigital’s electronic-prescription-service repositories, focusing on robust API development, data validation, and secure access control. They delivered FHIR-based prescription search APIs, integrated AWS CDK infrastructure, and enhanced backend reliability using TypeScript and Python. Their work included refining RBAC in the eps-prescription-tracker-ui, improving data parsing and validation, and automating regression testing for clinical workflows. By addressing schema integrity, error handling, and test automation, Orca UK ensured accurate prescription tracking and resilient deployments. Their technical depth is evident in the seamless integration of backend services, infrastructure as code, and comprehensive test coverage.

October 2025 focused on tightening data integrity, strengthening access control, and improving test reliability across three repositories. Key work included enhancing RBAC with hierarchical activity codes and granular permissions in the UI, stabilizing access controls via a targeted regression fix, and improving test clarity to prevent misinterpretation in QA. The work delivered concrete, business-value outcomes: fewer data parsing issues, more precise security controls, and more reliable regression tests.

June 2025 performance summary focusing on delivering robust NPPTS integration for the clinical-prescription-tracker and stabilizing core data pipelines and UI. Delivered a new NPPTS status retrieval pathway via a state machine integrated with Clinical View (GSUL call) and enhanced MedicationRequest processing with an optional performer, alongside refactoring the prescription search and updates to CDK infrastructure and schema generation scripts to support these capabilities. Addressed critical schema validation and notification reliability issues to improve data accuracy and workflow resilience. UI reliability improvements were completed to ensure correct resource URIs while safely deferring dosage instruction display until related fixes are implemented.

March 2025 achievements focused on expanding API capabilities for prescription data, stabilizing release processes, and increasing test coverage for CPTS FHIR endpoints. Delivered a new Prescription Search FHIR API with Spine integration, migrated deployment from SAM to CDK, and enhanced CI/CD to support CDK deployments. Implemented regression tests for CPTS Prescription Search FHIR endpoint and updated CI configurations to align with FHIR-specific requirements. Fixed critical release workflow issues (gh-pages checkout, environment secrets, deployment roles) to improve release reliability. These efforts collectively reduce time-to-value for new features, improve deployment reliability across environments, and strengthen quality assurance for FHIR-based prescription data workflows.

February 2025 monthly summary for NHSDigital/electronic-prescription-service-clinical-prescription-tracker. Focused on delivering targeted security-ops improvements with measurable business impact in a high-sensitivity healthcare workflow. 1) Key features delivered - Implemented Secret Scanning False Positive Mitigation by updating the .gitallowed configuration to exclude legitimate metadata patterns from secret-scanning tooling. Specifically added patterns for root and codeSystem attributes with versions 1.2 and 2.1 to prevent false positives. 2) Major bugs fixed - Resolved false positives in secret-scanning scans by refining detection rules; changes are scoped and non-breaking, with a single commit ensuring traceability. 3) Overall impact and accomplishments - Reduced security tooling noise, enabling faster CI/CD cycles and fewer manual triage efforts for the clinical-prescription-tracker project. - Improved accuracy of automated secret detection, helping maintain compliance while avoiding drain on developer productivity. - Clear audit trail with commit 60926aa52e4715f09f5158d4d0290fc30bb9458c (Chore: [AEA-0000] - Update gitallowed (#827)). 4) Technologies/skills demonstrated - Secret scanning tooling configuration and tuning (.gitallowed) - Pattern-based whitelisting for metadata attributes (root, codeSystem) with versioned values (1.2, 2.1) - Change management and traceability in a healthcare domain repository
