Summary
👤
Senior🎓
Top SchoolChu-yu Hsu is a software engineer with 11 years’ experience building production-scale ML and recommendation systems, currently optimizing global recommendation infrastructure at TikTok in Singapore. He has a strong track record of latency and quality improvements—e.g., redesigning a real-time recommender to cut latency from 12s to 36ms and boosting maP@10 from 3.1% to 9.4%—and experience deploying text-embedding, ALS and inverted-index solutions in low-latency production. Earlier roles span machine learning engineering at IBM and Emotibot, authoring practical guidance on recommenders, and founding an athleisure business where he built an in-house ERP and automated operations. He combines hands-on model engineering, production systems optimization, and product-minded entrepreneurship, and often focuses on measurable inference-performance gains rather than just algorithmic novelty.
