Worked on enhancing access control and documentation within the Shopware ecosystem, focusing on the shopware/meteor and shopware/docs repositories. Delivered an ACL helper and privilege checks for the Admin SDK, introducing a can() function and extending getAppInformation with a privileges field to enable fine-grained authorization for app integrations. Implemented comprehensive unit tests in TypeScript to ensure reliability of the new access control logic. Additionally, improved performance-related documentation in shopware/docs by clarifying prerequisites for cache invalidation workflows, reducing misconfiguration risks. Demonstrated a methodical approach to both security and documentation, leveraging JavaScript, TypeScript, and Markdown to support developer onboarding and integration.
