Worked on enhancing the reliability of macOS screenshot filename parsing in the badlogic/pi-mono repository, focusing on improving locale compatibility and automation for asset ingestion workflows. Addressed parsing errors by implementing case-insensitive matching for AM and PM markers, ensuring that both lowercase and uppercase variants are correctly recognized across different locales. Expanded the test suite to cover these scenarios, increasing confidence in cross-locale parsing accuracy. Consolidated these improvements into a targeted feature update, aligning with broader reliability goals. Utilized TypeScript and full stack development skills to deliver a robust solution that streamlines screenshot processing and reduces errors in automated environments.
