Worked on the TriliumNext/Trilium repository to deliver comprehensive German localization for both the server and client user interfaces, focusing on enhancing accessibility for German-speaking users. Leveraged JSON and Weblate to translate chat-related strings and error messages, achieving full coverage for the server and over ninety percent for the client. Established a documented localization workflow with explicit coverage tracking and reference URLs to streamline future updates. The work addressed internationalization needs by expanding language support, ensuring that the application could reach a broader audience. Skills applied included localization, software development, and translation, with an emphasis on workflow reliability and maintainability.
