PROFILE

Daria Mityagina

Daria Mityagina contributed to the openvinotoolkit/openvino and aobolensk/openvino repositories by developing and optimizing dynamic batching and inference features for the NPU plugin. She enhanced batch processing reliability by refactoring dynamic shape handling and aligning batch size management with tensor reallocations using C++ and Python. Daria introduced robust error handling and validation to prevent invalid models from reaching the compiler, and implemented user-facing warnings to guide optimal batching configurations. Her work included expanding end-to-end tests and updating metadata handling, resulting in improved throughput, reduced runtime errors, and safer deployment of dynamic workloads, demonstrating depth in backend and plugin development.

October 2025: OpenVINO NPU Plugin dynamic batching enhancements, export/import compatibility, and robust testing. Consolidated dynamic batching work across the Plugin and Compiler, introduced a new metadata version, and expanded end-to-end tests, including dynamic and unbounded batching and export/import behavior. Removed compile_tool workarounds, added dynamic shape checks utility in the single-image-test tool, and expanded test coverage to improve reliability and deployment confidence. Business value includes higher device utilization, faster, more reliable inference for dynamic workloads, and safer cross-version tooling compatibility.

August 2025 — OpenVINO repository updates focused on stabilizing dynamic model inference for the NPU plugin. Delivered a robust fix for dynamic model handling by aligning batch size management with tensor reallocations and refactoring the checks for input tensor size changes to improve reliability across dynamic workloads. The changes are captured in the commit '[NPU] Fix dynamic models regressions (#31583)' (d6727a7b87330a9105741fe47a095e9f43586581). Impact: higher reliability for customers deploying dynamic models on NPU, reduced runtime errors and churn, and improved predictability of performance. Technologies/skills demonstrated: C++, NPU plugin development, dynamic tensor management, regression debugging, and code refactoring for maintainability.
