Worked on stability and reliability improvements in ONNX Runtime, focusing on the QNN Execution Provider across microsoft/onnxruntime and intel/onnxruntime repositories. Addressed critical bugs in C++ and Python, such as correcting PoolOpBuilder to handle 5D input shapes and prevent assertion failures during pooling operations. Developed a utility to detect zero-dimension tensors in Concat, reducing runtime errors, and enhanced the static quantization runner by fixing input order and registering CumSum for quantization. Emphasized robust backend development, algorithm design, and model calibration, delivering targeted fixes that improved inference accuracy and reduced debugging time for edge-case scenarios in production environments.

In August 2025, delivered a focused bug fix for the PoolOpBuilder in ONNX Runtime's QNN Execution Provider to correctly handle 5D input shapes. The change revises input-shape checks and pooling call paths to ensure accurate output shape calculation, preventing misinference and assertion failures in Debug builds. This improves model fidelity and stability for 5D tensor pooling across workloads, reducing debugging time for contributors and enhancing reliability in production inference.
