Worked on the OpenTripPlanner repository to enhance routing reliability and user experience by addressing a key performance issue. Focused on Java development and leveraging Maven for build management, the developer reverted the street routing timeout to five seconds, ensuring routing requests are handled within a predictable timeframe. This targeted bug fix, implemented through a disciplined pull request and code review process, restored consistent routing latency and improved the overall user experience. By standardizing the timeout policy, the work established a stable foundation for future performance optimizations. Skills applied included continuous integration, GraphQL API usage, and effective version control practices.
