Angel Fernandez delivered Spanish localization features for the TriliumNext/Trilium repository, focusing on both client and server UI translation. Over two months, Angel implemented comprehensive Spanish language support using JSON and Weblate, achieving near-complete coverage of interface strings and enhancing accessibility for Spanish-speaking users. The work involved coordinating translation updates across the codebase, integrating localization workflows, and ensuring consistency between client and server components. By establishing a reproducible translation process and improving the localization infrastructure, Angel enabled scalable internationalization for future releases. The engineering effort addressed global accessibility needs and reduced language-related support requirements without introducing new bugs.
