PROFILE
Even Zhou
Over four months, contributed to the ping1jing2/sglang repository by engineering and stabilizing NPU-accelerated deep learning workflows, with a focus on model quantization, deployment, and performance optimization. Addressed reliability issues in INT8 quantization and enhanced support for models like Qwen3 and DeepSeek on Ascend NPUs. Improved CI/CD pipelines and Docker-based deployment, ensuring robust dependency management and reproducible builds. Leveraged Python, C++, and Shell scripting to implement bug fixes, optimize memory management, and streamline graph execution. The work enabled broader hardware compatibility, reduced runtime failures, and established a foundation for scalable, high-performance model inference on distributed NPU systems.
