Building useful things at the edge of AI and software

I care about the layer between a capable model and a dependable product: the harness, feedback loops, native tools, benchmarks, and small automations that make AI genuinely useful.

Today I am exploring AI games and shipping practical developer tools. I study at HKUST (Guangzhou) and previously interned at DJI and Tencent.
