PROFILE
Max Gosau
Worked on OpenTripPlanner over two months, focusing on backend enhancements for real-time transit data reliability and schedule handling. Delivered four features, including a new SCHEDULED state for stops lacking EstimatedCallType data, which improved journey planning when information was incomplete. Refactored real-time trip state management by introducing a value class to encapsulate state flags, aligning related classes for maintainability. Enhanced SIRI integration to support simultaneous added and canceled trip states, and improved missing data handling with robust fallback logic and expanded test coverage. Utilized Java, Maven, and GraphQL, emphasizing software architecture, real-time systems, and test automation throughout the development process.
