During April 2025, Chen Ziqiang contributed to the nndeploy/nndeploy repository by addressing a critical issue in the operator registration process for the AveragePool operation. He identified and corrected a typo in the operator type definition within the C++ codebase, changing kOpTypeAvaragePool to kOpTypeAveragePool in op_param.cc. This bug fix ensured accurate identification and consistent registration of the AveragePool operator throughout the deployment pipeline, reducing the risk of runtime errors. Chen applied his skills in C++ and code refactoring, maintaining clear documentation and commit messages to support code review and future maintenance, demonstrating careful attention to codebase correctness.
