Worked on the software-mansion/react-native-screens repository, focusing on Android development with React Native and UI/UX design using Kotlin. Addressed a complex bug related to display density handling by implementing per-view density-aware pixel-to-dp conversion within FabricEnabledViewGroup. This solution improved UI rendering across devices with varying display densities, such as Samsung DeX and external monitors, ensuring that content fills available space rather than collapsing into a small box. The approach included a safe fallback to global density when needed and preserved single-display behavior. Comprehensive validation involved multi-display reproduction, extensive window-size testing, and preparation of visual documentation for continuous integration readiness.
