Worked on the w3c/wcag repository to address a cross-platform build issue in the 11ty asset generation pipeline. Focused on improving the reliability of the build process by replacing hardcoded path separators with the platform’s native separator, this change resolved a Windows-specific bug that previously caused build failures and inconsistent asset paths across operating systems. Utilized Node.js and TypeScript to implement the fix, ensuring stable builds on Windows, macOS, and Linux. The update enhanced continuous integration reliability and reduced iteration time for developers, demonstrating a methodical approach to cross-platform compatibility and robust full stack development practices within the project.
