About

A little about who I am

Hi there, welcome! 👋 I turn coffee and curiosity into code, and “what if we built…” into “okay, it’s live.”

These days I’m a C++ Software Engineer at Huawei Hong Kong Research Center, building MLIR-based AI compilers that squeeze every last cycle out of Ascend NPUs.

✨With great optimization comes great responsibility.✨
