Worked on the Kareadita/Kavita repository to deliver Spanish localization and UI accessibility enhancements, focusing on expanding usability for Spanish-speaking users. Implemented translations for UI strings, error messages, and settings related to reading profiles and PDF reader options, using JSON to structure localized content. Integrated a Weblate-driven translation workflow, ensuring that future internationalization efforts can build on reusable localization patterns. The work emphasized front end development and accessibility, reducing support friction and laying a foundation for broader market reach. No major bugs were reported during this period, reflecting a focused contribution on feature delivery and internationalization readiness within the project.
