In February 2026, Bartosz Hanc expanded the computer vision capabilities of the software-mansion/react-native-executorch repository by implementing semantic segmentation model support for DeeplabV3, LRASPP, and FCN across both quantized and FP32 runtimes. Working primarily in TypeScript and leveraging React Native, Bartosz developed and validated end-to-end pipelines for iOS and Android, ensuring production readiness and maintainability. He contributed comprehensive documentation, inline code comments, and clear deprecation notes to guide future development. The work included preparing HuggingFace model pages to streamline integration, and involved close cross-team collaboration, resulting in a robust, release-ready enhancement for mobile computer vision applications.
