William Lee is a Sr. Program Manager based in Bellevue with three years of focused experience bridging machine learning operations and large-scale program delivery. He led organization and quality for 100+ ML annotators and contributed to LLM development, fine-tuning, and evaluation during a multi-year tenure at Amazon. Known for running complex, global annotation and localization initiatives, he has repeatedly scaled distributed contributor networks and managed multimillion-dollar forecasting and budgeting.
