At 588ku.com (Pngtree), I owned the content lifecycle and category P&L, managing a EUR 400K-600K annual budget. I tested pricing and funnel entry points, helping increase paid subscriptions by 96%.
At Telus Digital, I improved generative AI model accuracy and reasoning consistency through RLHF/SFT workflows and high-fidelity Golden Datasets. I also founded the Douban.com community, which grew to 200K+ members and was featured in The Wall Street Journal and China Daily.
