Worked on the Shopify/extensions-templates repository to streamline extension configuration by deprecating and removing the Marketing Activity Extension Template. Focused on template management using Liquid, the effort targeted repository hygiene by eliminating outdated fields such as name, handle, title, description, and preview data types from the codebase. This cleanup reduced configuration complexity and helped prevent confusion for future developers. The changes were implemented through a focused commit, emphasizing maintainability and a smoother onboarding experience. No major bugs were addressed during this period, as the primary goal was to improve code quality and simplify future extension development within the repository.
