Developed a GraphQL mock data model for the Quotes List View within the commercetools/test-data repository, focusing on enhancing QA and integration testing for the MC Settings service. The work centered on the my-view module, where a builder pattern, field configurations, and TypeScript type definitions were implemented to generate realistic mock data for the Quotes List View exposed via the GraphQL API. Accompanying tests were created to validate the API surface, supporting more reliable and consistent test data. This feature improved validation cycles and data consistency across MC Settings, leveraging skills in API mocking, GraphQL, and TypeScript software development.
