During this period, contributed to the root-project/root repository by enhancing the SOFIE ONNX testing framework with targeted GELU operator unit tests. The work involved integrating new tests into the central suite using C++ and ONNX, consolidating coverage and improving maintainability by removing redundant standalone files. By adding a precise erf-based reference output and aligning tests with recent pull requests, the changes strengthened regression safety and ensured compatibility across ONNX execution paths. This approach increased reliability in model inference and enabled earlier detection of regressions, reflecting a focus on robust software testing and effective use of unit testing methodologies.
