Rockstar🎓
Top SchoolYue Sun is a Machine Learning Engineer with a Ph.D. from the University of Washington and 10 years of experience building production ML systems for Ads and LLM products at Reddit, Calendly, and Microsoft. She designs large-scale retrieval and ranking pipelines (TensorFlow, Spark, Ray, BigQuery) and integrates user-interest expansion and embeddings into real-time serving systems that handle billions of events. At Calendly she shipped token-efficient LLM meeting summarization and multi-agent orchestration, and at Microsoft she improved ad-query generation and raised income-prediction AUC via BERT and LLM labeling. Her research background spans theoretical guarantees in meta-learning and control, linking rigorous theory to practical implementations in PyTorch and Azure. She also contributes to well-known open-source Bot Framework projects, adding robust declarative tests and calendar skill improvements that reflect a full-stack mindset. Based in Falls Church, VA, Yue blends deep academic foundations with pragmatic product impact across recommendation, retrieval, and LLM tooling.
