PROFILE
Arnljot Arntsen
Worked on the OpenTripPlanner repository over a two-month period, focusing on stabilizing cross-platform file handling and improving Windows compatibility. Addressed critical build failures by normalizing line endings and ensuring consistent file writes across Windows, macOS, and Linux environments. Refactored error handling and enhanced JSON pretty printing to improve reliability and readability of output files. Applied Java and unit testing skills to deliver robust debugging and maintainability improvements, reducing environment-specific issues and strengthening CI stability. The work emphasized code hygiene and developer experience, particularly for Windows contributors, and resulted in more reliable cross-platform file IO and fewer platform-specific bugs.
