Worked on the keras-team/keras repository to modernize and unify the model export workflow across multiple backends. Over two months, delivered a refactor of the ExportArchive class into a dispatcher pattern, enabling seamless export to TensorFlow, JAX, and Torch backends. Leveraged Python and backend development skills to implement centralized export logic, reduce technical debt, and support future extensibility. Migrated the export system to use NeptuneModel, removing the Orbax dependency and improving maintainability. The work established a flexible, scalable architecture for model export, enhancing cross-backend consistency and laying the foundation for additional exporter integrations with minimal disruption.

Feb 1, 2026February 2026 performance summary for keras-team/keras: Delivered a pivotal refactor that unifies model export across backends by turning the ExportArchive class into a dispatcher for multiple export backends (TensorFlow, JAX, Torch). This work enhances flexibility, usability, and cross-backend consistency of Keras model exporting, while laying groundwork for the Keras 3 export workflow. No explicit major bug fixes were recorded in this scope; the refactor reduces backend-specific export issues and stabilizes the export pipeline. Overall, the update streamlines multi-backend deployment and improves developer experience across teams.
