Worked on the Shopify/cli repository to address data integrity issues in development store fetches by implementing a targeted bug fix. Updated GraphQL queries and TypeScript definitions to replace the deprecated 'properties' field with 'accessibleShops', ensuring alignment with the latest API schema. This change reduced the risk of misfetches and data inconsistencies, directly improving the reliability of core CLI workflows and minimizing potential runtime errors and CI failures. The work demonstrated a focused approach to API integration, leveraging skills in GraphQL and TypeScript to enhance data reliability and maintain compatibility with evolving backend systems during the development cycle.
