David McGrath worked on the govuk-one-login/account-interventions-service repository, delivering six features over four months focused on security, testing, and automation. He implemented security hardening by disabling npm and yarn scripts, automated dependency updates, and stabilized the Jest-based testing infrastructure using JavaScript and TypeScript. David enhanced CI/CD workflows by introducing automated Pact binary installation for contract testing and enforced code quality through a Quality Gate Manifest. He also upgraded the Dynatrace Lambda Layer to improve AWS Lambda monitoring. His work emphasized maintainability, reproducibility, and risk reduction, demonstrating depth in dependency management, infrastructure as code, and continuous integration practices.
