Worked on the ROCm/onnxruntime repository to enhance the stability and correctness of model export workflows involving external data files. Focused on resolving a bug in the export path resolution logic, ensuring that models referencing external data are exported with accurate file paths. This targeted fix addressed failures in the graph_save() function, reducing export-time errors and improving downstream reliability. Applied C++ and debugging skills to validate and tighten the end-to-end export process, aligning the codebase with best practices for external data handling. The work contributed to overall code maintainability and robustness in the software development lifecycle for model export features.
