Worked on stabilizing and improving the reliability of the matsim-org/matsim-libs RailSim module over a three-month period, focusing on bug fixes rather than new feature development. Addressed concurrency issues and infinite loop risks in Java-based simulation code, enhancing event sequencing and test reliability across CI/CD pipelines. Improved logging clarity during rerouting scenarios to aid troubleshooting without altering core routing logic. Extended integration and simulation tests to cover edge cases such as end-of-line vehicle arrivals and deadlock avoidance, using test-driven development and integration testing. The work emphasized maintainability, cross-platform stability, and clear diagnostics, leveraging skills in Java, concurrency, and logging.
