During November 2025, Py Mc20 focused on enhancing the copper-project/copper-rs repository by refactoring its graph APIs to introduce a CuDirection enum, enabling more flexible graph traversal. Working primarily in Rust, Py Mc20 designed and implemented new CuGraph utilities that allow developers to retrieve neighbor IDs, count incoming and outgoing neighbors, check for connection existence, and locate nodes by name. This API refactoring improved the usability and maintainability of graph-related features, laying a foundation for future analytics. The work demonstrated depth in API design and graph data structures, consolidating usage patterns across the codebase and supporting more efficient feature development.
