Worked on enhancing the robustness and observability of ONNX Runtime’s QNN Execution Provider and ROCm/onnxruntime repositories over a two-month period. Addressed edge-case stability by implementing dedicated 0-dimension tensor handling for the Concat operation, introducing a ConcatOpBuilder and comprehensive unit tests using C++. Later, improved backend development by refining logging fidelity in ROCm/onnxruntime, ensuring ETW log levels take precedence only when they provide higher detail than QNN, which reduced log noise and improved diagnostic accuracy. Demonstrated skills in C++, backend development, and telemetry instrumentation, focusing on precise, maintainable code changes that support reliability and faster issue triage.
