// About 02

I’m Alex. I build AI products in Hong Kong.

8+ years driving enterprise-scale products at TikTok, Hulu/Disney, and JD.com. Specializing in LLM copilots, ad decisioning, and ML-powered platforms that move real metrics.

Currently shipping Arena Copilot, an LLM-powered chatbot for internal operations using RAG and agent capabilities, automating Q&A and task execution across LIVE operations teams.

Previously led Unified Selection at Hulu, integrating Hulu’s ad inventory with third-party DSPs via real-time bidding, with phased yield optimization driving measurable revenue growth.
