During March 2025, Angel Ocariz enhanced accessibility and documentation across Stirling-Tools/Stirling-PDF and internetarchive/openlibrary by delivering Spanish localization improvements and comprehensive documentation updates. For Stirling-PDF, Angel refined and completed Spanish translations, particularly clarifying survey-related phrases to improve usability for Spanish-speaking users. In OpenLibrary, Angel authored a full Spanish translation of the README, covering project structure, installation, and contribution guidelines to support developer onboarding. These contributions were implemented using Java and Markdown, leveraging skills in documentation, internationalization, and localization. The work demonstrated a methodical, cross-repository approach to reducing language barriers and strengthening project guidance without introducing new bugs.
