Summary
👤
Senior🎓
Top SchoolWeijie Liu is a Technical Lead Manager in New York with nine years of experience building large-scale recommendation, ranking, and ads systems. He currently leads a team of about 10 engineers at Shopee, driving the back-end of personalized feed, livestream, and video recommendation pipelines from 0 to 1 and shipping DL-based recall through re-ranking modules. Prior roles at Google and Facebook span big-data infra and ML-driven products—he owned Google Maps’ Popular Times (100M+ DAU) and worked on ads quality at PB-scale. A lifelong learner who also contributes to open-source TypeScript type definitions (notably to DefinitelyTyped for a WeChat Mini Program plugin), he blends hands-on coding with product-minded system design. He prefers not to be contacted about opportunities and focuses on scalable ML/infra challenges and ads/recommendation problems.
