Worked on the ensdomains/ens-app-v3 repository to deliver comprehensive Spanish localization for the user interface, enhancing accessibility for Spanish-speaking users and supporting broader market reach. Focused on internationalization and localization, the work involved translating eleven distinct UI JSON files, ensuring each file was committed separately for clear traceability and future scalability. Leveraged JSON for structured data management and maintained a disciplined Git-based workflow to support ongoing multilingual development. No major bugs were addressed during this period, as the primary objective was to improve user experience through targeted localization efforts and to establish a robust, maintainable i18n process for the application.
