AI engineer shipping production LLM agents at enterprise scale. Reached out to by Anthropic as one of GenDigital's top Claude Code users. Native Mandarin speaker, born Beijing, US-educated (Babson + Olin), EU-resident.
- Production LLM agent (NEMO) — LangGraph, 12 tools, human-in-the-loop approval gates, Redis state, Langfuse observability. Serving 3 brands (Norton, Avast, AVG) across 30+ languages to 500M+ users
- 5+ MCP servers (Python/FastMCP) — bridging LLMs to SFMC, Jira, BigQuery, Postgres, enterprise search across 40+ data sources
- Deterministic eval methodology (Langfuse) — biased toward interesting cases, not random. Build-stamped traces correlate quality regressions with specific releases
- better-litellm — LLM proxy adopted org-wide. CTO engineering leadership proposed deploying server-side as zero-config infrastructure. Found and fixed command injection vulnerability before shipping
- ML experiment operations — Configured Product Recommender A/B program (7.5%+ stat-sig bookings uplift). Operationalized Segmented Discounting pricing optimization through CDP/IPM
