Hasan Beytullah Kara developed the initial Turkish localization for Trilium Notes, focusing on both the server and website components within the TriliumNext/Trilium repository. He established a foundational workflow for localization using JSON and integrated translation management through Weblate, enabling traceable and incremental translation updates. His work included organizing and translating key interface strings, with progress tracked via commit history for transparency. By addressing the technical requirements of multilingual support and preparing the codebase for future localization-driven user experience improvements, Hasan demonstrated proficiency in localization, software development, and translation, delivering a focused but foundational contribution over a one-month period.
