Worked on the City-of-Helsinki/helsinki-design-system repository to deliver secure, provenance-enabled publishing workflows by implementing patchrelease branch support and OIDC-based trusted publishing, removing manual NPM_TOKEN requirements and deprecated workflows. Upgraded Lerna and enhanced npm provenance metadata to improve release reliability and auditability. In the City-of-Helsinki/linkedcomponents-ui repository, enhanced cookie consent management by adding support for authentication and analytics cookies, providing clearer data management signals for users. Focused on security hardening and workflow modernization using JavaScript, YAML scripting, and GitHub Actions, with an emphasis on CI/CD, DevOps practices, and robust package management to streamline and secure the release process.
