Roberto Bochet focused on stabilizing the PDF export workflow for the slidevjs/slidev repository, addressing a critical bug that previously caused exported PDFs to be saved in incorrect directories and resulted in broken download links. Using TypeScript and full stack development skills, Roberto investigated the exportFilename path resolution, implemented a fix to ensure customizable filenames and correct output directory handling, and validated the end-to-end export process. This work improved the reliability of PDF exports, reduced support issues for end users, and established a maintainable export path, laying the groundwork for future enhancements to the export functionality within the project.
