Worked on Stirling-Tools/Stirling-PDF to deliver a Bulgarian localization update, focusing on aligning the user interface strings with current translations to enhance accessibility for Bulgarian-speaking users. The update involved modifying the messages_bg_BG.properties file using Java, with attention to internationalization and localization best practices. All changes were consolidated into a single change-set to streamline the quality assurance and release process. No major bugs were addressed during this period, as the primary objective was to improve user experience consistency and clarity for Bulgarian speakers. The work demonstrated a methodical approach to language support within the existing codebase, emphasizing maintainability and usability.
