Bridging atom factories and token factories. #

Hi, I’m Chung-Hao (CH) Lee 李崇豪 — based in Sydney.

I started on factory floors and grew into AI systems. At Pegatron Suzhou, I ran a 15-person team operating an AIoT manufacturing line producing 2M units per year. At Wistron Taipei — a global Tier-1 server ODM (Dell, HPE) — I delivered $1.2M in annual cost savings through AI-driven predictive maintenance across 40B+ sensor data records, and deployed LLM for log analysis at scale. Now at TikTok Sydney, I built the Live RCA Copilot human-AI collaboration system and platform from 0 to 1.

What carries across these roles isn’t a domain — it’s a method I’ve come to call “Analysis + Process”: deconstructing ambiguous problems into measurable parts (analysis), then designing repeatable workflows that close the loop (process). I wrote about why these two keywords define my work — the Wistron “No Power recall plunge” case is the canonical example.

What I Build #

At Work #

• TikTok (2025 – present) — Built RCA Copilot 0→1, integrating multi-agent orchestration, hallucination engineering, and dual GUI/CLI interfaces. Lifted adult-content model F1 by +38%. Established a three-tier inspection framework achieving 80%+ ground-truth consistency and 95% model accuracy across 35 models.
• Wistron (2022 – 2024) — Three-phase industrial AI program (smart diagnosis → predictive forecasting → knowledge consolidation) across 6 cross-functional teams. 70% debug efficiency lift, 50% return-to-repair reduction, $1.2M annual savings.
• Pegatron (2018 – 2020) — 15-person team, 2M AIoT units / year, end-to-end SMT + FATP process control in Suzhou.

Built in Public — Extending the Bridge #

• multi-lens-thinking — A six-stage AI reasoning pipeline routing questions through four parallel analytical lenses.
• WikiPolyDraft — Open-source AI-drafted Wikipedia translation tool. First article: Barangaroo (Sydney). Same “AI drafts, human lands it” philosophy — applied to cross-language civic knowledge.
• My Daily Digest — Automated daily intelligence on AI data center infrastructure (NEXTDC, AirTrunk, Equinix AU, AEMC/AEMO grid signals), geopolitical risk, and AI builder updates. Built to keep my own atom × token thesis live.
