Worked on enhancing the developer experience for GovUK One Login by improving authentication documentation within the govuk-one-login/tech-docs repository. Focused on clarifying integration flows and reducing onboarding friction, the work included detailed guidance on validating ID token signatures using a public key and updates to the changelog to better reflect authentication and service integration changes. Leveraged Ruby and Markdown to deliver these documentation enhancements, emphasizing security and technical clarity. The approach prioritized clear technical writing and addressed feedback by refining headings and resolving comment suggestions, ultimately supporting integrators in understanding authentication processes and aligning documentation with current security practices.
