Clarissa John developed automation and security features for the NHSDigital/identity-service-jwks repository over a two-month period. She built Python scripts to convert SBOM and Grype vulnerability scan outputs from JSON to CSV, integrating these into GitHub Actions for automated, auditable reporting within CI/CD pipelines. Clarissa also enhanced documentation to support these new workflows and data formats. In addition, she implemented a public-key-based JWT verification flow for the Clinical Data Gateway API proof of concept, using JSON configuration to strengthen authentication security. Her work demonstrated depth in Python scripting, security implementation, and automation, addressing both supply chain visibility and API security.
