I work at the intersection of data, content, and growth — the throughline across every role has been turning unstructured operational problems into measurable, repeatable systems.

Most recently, as an AI Data Analyst at Telus Digital, I worked on generative AI alignment: improving model accuracy and chain-of-thought reasoning consistency through RLHF/SFT workflows and high-fidelity golden datasets, and optimizing red-teaming and data-backflow strategies that raised content safety compliance from 82% to 95%. This built on earlier trust & safety work at Baidu, where I audited 800+ UGC posts daily at 99% accuracy and trained 1,000+ creators on platform policy — so I'm equally comfortable in AI training/evaluation roles, content moderation, and policy/safety operations.

On the growth and product side, at 588ku.com I owned end-to-end category P&L — contributor recruitment, training, payroll, production scheduling, and asset retirement — while running landing page and funnel experiments that drove a 96% lift in paid subscription conversion. I also built an RFM segmentation model across 3,000+ partners to prioritize high-value relationships and improve partner revenue, which is the closest analog to RevOps, partner/vendor management, and lifecycle CRM marketing.

Earlier in my career I led digital transformation and localized SEO for a German brand's APAC market entry (40% traffic growth), redesigned CRM lead-scoring logic to automate sales qualification (+20% post-event satisfaction), and ran social/content growth for 12 accounts reaching up to 6M views per post. I also founded and scaled an independent community to 200,000+ members from zero, featured in The Wall Street Journal and China Daily.

I'm interested in roles across: AI data/alignment & LLM training, trust & safety/content policy, growth marketing & conversion rate optimization, RevOps & partner operations, marketing automation/CRM, and content/category operations. Tools: SQL, Google Analytics, HubSpot, Python/Excel automation, AI agent tooling (Claude Code, Codex). Languages: Mandarin (native), English (C1), German (A2). Full work authorization for Germany.
