Worked on the huggingface/xet-core repository to introduce serialization support for core data structures, focusing on CasObject and CasObjectInfo. Leveraged Rust and the serde library to implement serialization by deriving Serialize, enabling these objects to be stored and transmitted efficiently. The approach established a persistence-ready data model, laying the groundwork for future cross-service data exchange and integration within the codebase. All engineering efforts during the period centered on stabilizing and strengthening the serialization path, with no major bug fixes required. Utilized Cargo for dependency management and ensured the new serialization capabilities aligned with the repository’s interoperability goals.
