During February 2026, Badhill contributed to the OpenTripPlanner repository by enhancing the Transmodel API Cost scalar to support both string and integer duration values, addressing type compatibility issues and reducing integration friction for API clients. Working primarily with Java and GraphQL, Badhill implemented improved parsing logic to prevent NullPointerExceptions when handling integer durations, thereby increasing runtime reliability. Additionally, Badhill updated Markdown documentation to clarify the use of large periods for unbounded transit service configurations, providing clearer guidance for long-duration scenarios. The work demonstrated a solid understanding of backend development and configuration management, with thoughtful attention to both code and documentation quality.
