Hi, I'm an industrial engineering master's graduate who turns messy operational data into decisions that actually ship. I work at the intersection of supply chain analytics, optimization modeling, and business intelligence.
University of Washington · Seattle
SF Express Co., Ltd. · Shenzhen
CITIC Securities Co., Ltd. · GuangzhouBilingual travel companion PWA for Chinese-speaking parents visiting international students in the US. Real-time photo translation of menus, signs, and notices via Claude Vision API. Offline-first, deployed via WeChat link — no installation required.
Formulated a 96-state MDP to optimize vocabulary scheduling, calibrated on 220M real learning interactions. Best threshold policy recovered 97% of optimal performance at +2.7% cost overhead. Discovered the optimal policy is non-monotone — a "desirable difficulty" effect.
Two-phase intelligent framework for warehouse AGV task allocation. CBBA bidding algorithm for task assignment + Jump Point Search for shortest-path planning. Reduced average delivery time by 15%.
$55K government-funded contract. Delivered 20% accident reduction and 27% faster emergency response through PSO-optimized Bayesian networks and knowledge graphs built with cross-functional teams.
THE IDEA
My parents visited me in the US for the first time. They don't speak English, don't use Google Maps, and weren't sure what to do at customs. I spent half the trip translating on the fly — and realized there was no app that actually solved this for Chinese families.
THE BUILD
ParentPass is a PWA — no App Store, no install friction. It works offline because airports have spotty wifi and parents shouldn't have to worry about connectivity. The core flows: trip itinerary with flight info, airport navigation prompts in Chinese, a phrasebook for common travel situations, and an SOS screen with emergency contacts and English instructions they can hand to someone nearby.
SYSTEM DESIGN
Built with React + Vite, deployed on Vercel. All content is bilingual — every string has a Chinese and English version, toggled at the app level. Service worker caches all routes and static assets for full offline support. State is localStorage-backed so trip details persist between sessions without needing a backend.
A small collection, a future garden. Blame it on Seattle :)








On weekends, you'll find me on a court, a trail, or out in nature.
Hiring, building something, or just want to think through a problem together? Drop me a line — I reply to everything.
