James McBroom developed and refined features across two repositories, focusing on both user experience and maintainability. In the theopensystemslab/planx-new project, he implemented an address-based LPA Lookup by integrating the Planning Data API with a React frontend, enabling users to retrieve local planning authority information through intuitive address search. He also removed deprecated redacted data export endpoints, simplifying the API and reducing technical debt. In astronomer/airflow, James enhanced project documentation by officially attributing the City of Detroit as a user, improving transparency for new adopters. His work utilized TypeScript, Node.js, and REST APIs, demonstrating thoughtful, maintainable engineering.
