Rockstar🎓
Top SchoolJames Hills is an engineering leader and manager currently heading Forward Deployed Engineering (FDE) at OpenAI in New York, with a fast-rising two-year career focused on applying ML in production. He progressed from Solutions Architect to Tech Lead and now FDE Manager, combining hands-on model fine-tuning and full-stack contributions with people and project leadership. His open-source work includes notable contributions to the popular openai/openai-cookbook, adding notebooks and examples around function-calling fine-tuning and synthetic data generation. Prior to OpenAI he built data-science expertise at QuantumBlack (McKinsey) after early quantitative roles in finance and research, bringing strong applied-math foundations from Yale. Colleagues know him for translating complex model capabilities into practical, documented examples that help teams ship, not just prototype. Outside work he has a history of entrepreneurial and community roles—running an eBay business and coaching youth lacrosse—suggesting a bias for action and teaching.
