Summary
👤
Senior🎓
Top SchoolQinxing He is a Machine Learning Engineer based in Singapore with 8 years of hands-on experience building NLP-driven search, recommendation systems, and LLM integrations across high-scale consumer products. Having shipped end-to-end recommender pipelines and chatbots at Shopee and developed LLM-for-recsys solutions at Huawei before joining TikTok, he combines strong production engineering (Redis, Kafka, MySQL, Elasticsearch) with state-of-the-art algorithm design. His work has measurably improved CTR and resolution metrics across multi-country, multi-language deployments, and he is comfortable driving projects from prototyping to optimization. Trained at NUS and USTC with international study at UC San Diego, he brings both research foundations and pragmatic engineering judgement—and a quiet “fighting” ethos reflected in his GitHub bio.
