Worked on the huggingface/lerobot and Genesis-Embodied-AI/Genesis repositories, focusing on data handling, caching, and localization. Enhanced episode cache verification in lerobot by optimizing retrieval of unique episode indices, reducing overhead and improving cache performance using Python and dataset management techniques. Introduced a dataset revision validity check to strengthen error handling and ensure robust data loading. In Genesis, contributed multilingual installation instructions for the uv package manager across translated Markdown README files, improving onboarding for non-English users and supporting localization goals. Demonstrated attention to documentation quality, Python package management, and workflow consistency, delivering targeted improvements that addressed reliability and accessibility.
