Anders Østby contributed to several NAV repositories by focusing on frontend stability, CI/CD security, and automated dependency management. In navikt/k9-sak-web, he removed deprecated enum values from React components using TypeScript and JavaScript, aligning the frontend with backend changes and preventing build failures. For navikt/sif-gha-workflows, Anders enhanced GitHub Actions workflows by migrating authentication to a dedicated read-only token, reducing credential exposure and improving security. In navikt/k9-abakus, he configured Dependabot to access the GitHub Container Registry via YAML-based registry settings, streamlining dependency updates. His work demonstrated depth in CI/CD, dependency management, and frontend development across multiple codebases.
