Summary
👤
Senior🎓
Top SchoolWilliam Wu is a Principal Data Scientist based in Singapore with a decade of experience building large-scale recommendation and advertising systems, from CTR/CVR models to fraud detection and promo optimization. He combines deep academic training in computer software and theory with hands-on engineering—shipping production ML pipelines, real-time user representation platforms, and an offline feature store at Grab. William has driven measurable business impact (e.g., double-digit CTR/CVR uplifts, 12% error reduction in supply forecasting) while scaling systems to handle high throughput and low latency. He also contributes to open-source tooling—helping develop the TabNine Jupyter extension—and has led cross-functional teams and mentored engineers, blending model innovation (PNN, multi-task networks) with pragmatic deployment (Kubernetes, TensorFlow, Spark). Quick to learn and focused on industrializing research, he thrives on turning complex algorithms into reliable, production-grade products.
