Christian van der Zee developed comprehensive Single Sign-On (SSO) onboarding documentation for Authentik integration within the scaleway/docs-content repository. Focusing on clarity and accuracy, Christian authored a new how-to guide in Markdown, detailing setup steps and requirements to streamline SSO adoption. He updated existing documentation to align with identity management best practices, corrected metadata, and improved navigation by adding a dedicated menu entry. Through technical writing and close collaboration with IAM and documentation teams, Christian ensured the guidance reduced onboarding time and support needs. The work demonstrated depth in documentation, technical communication, and cross-functional alignment, supporting reliable SSO implementation.
