What I'm looking for

I seek a product-focused role leading LLM evaluation and large-scale experimentation, applying causal analytics and A/B testing to drive measurable model and business impact within a collaborative, impact-oriented AI team.

I am a senior data scientist with 5+ years at leading tech firms, specializing in LLM performance optimization, causal analytics, and large-scale experimentation.

At Tencent and Kuaishou I designed evaluation benchmarks and prompts and researched ranking algorithms (Elo/TrueSkill) for robust LLM assessment. I developed A/B testing systems, built monitoring dashboards, and managed evaluation datasets (cleaning, Hive storage).

I optimize recommendation efficiency and ad product performance through causal inference, uplift modeling, and advertiser lifecycle analysis, supporting high-impact campaigns. I seek roles where I can lead LLM evaluation and experimentation to drive measurable model and business improvements.
