Shiro focused on stabilizing and refactoring the club information update flow in the academic-relations/ar-002-clubs repository, aligning form context types and clarifying field naming to reduce maintenance complexity. They improved the frontend by updating React components and TypeScript types, ensuring that updates to club descriptions and room passwords followed a consistent data structure. In the sparcs-kaist/clubs repository, Shiro simplified the testing environment by cleaning up submodules and mocks, and restored role-based mock access tokens to enable realistic test coverage. Their work demonstrated depth in API integration, frontend development, and mocking, resulting in more reliable and maintainable user-facing features.
