During October 2025, Nelahian focused on improving the stability of the TabList component in the BouyguesTelecom/trilogy repository. Addressing a specific UI bug, Nelahian implemented a targeted null-check to handle scenarios where the first tab, at index zero, might be missing. This change prevented runtime crashes in dynamic tab configurations, ensuring the component could gracefully handle edge cases without error. Working primarily with React Native and leveraging both JavaScript and TypeScript, Nelahian’s contribution enhanced the reliability of the frontend codebase. The work demonstrated careful attention to defensive programming, though the scope was limited to a single, well-defined bug fix.
