Worked on the cedar-policy/cedar repository to enhance the reliability of graph visualization in policy analysis tools. Focused on back end development using Rust, this developer addressed a bug that previously caused edges to appear between unrelated entities, which led to user confusion. By refining the edge rendering logic, they ensured that lines are now drawn only between entities with a parent-child relationship, resulting in clearer and more accurate policy graphs. The solution maintained code quality through adherence to review and signing practices, aligning with the project’s goals of improving data relationship visibility and supporting more efficient policy analysis workflows.
