During April 2026, contributed to the GIScience/openrouteservice repository by developing a feature that enhanced track grade parsing, enabling the system to robustly handle multiple grade formats and improve the accuracy of grade level determination. The work focused on refining parsing logic using Java and JUnit, resulting in more reliable route data processing and supporting better downstream routing decisions. This targeted enhancement improved the quality of analytics and user experience by ensuring consistent interpretation of track grades. Collaboration was demonstrated through co-authored commits, and the approach emphasized code quality and maintainability, with a strong focus on software development and unit testing practices.
