During February 2025, Luandro developed a language metadata display feature for the digidem/comapeo-mobile repository, focusing on the Wayamu/Tumucumaque mosaics within the mobile app. He extended the data model by adding new language fields and updated the user interface to present this metadata, thereby enriching the mosaics’ data and supporting improved content discovery. Working primarily with JavaScript and leveraging his mobile development expertise, Luandro aligned the implementation with ongoing metadata enrichment and localization initiatives. The work demonstrated a focused, well-scoped engineering effort, addressing a specific need for enhanced data richness without introducing major bugs or requiring extensive bug fixes.
