At Trip.com, I built and operated content-safety workflows for travel reviews, listings, and community posts. I designed report intake, triage, and review queues to route high-risk cases by severity and SLA, and partnered with policy, operations, and product to reduce duplicate and invalid reports.
At Learnable.ai, I built AI auto-grading for homework and exams, from submission intake through model-assisted scoring and structured feedback. At Pinduoduo, I worked on account, profile, and related APIs in the user module of a high-traffic e-commerce app.
