Joon Lee
Head of Forward Deployed Engineering
Forward deployed engineering leader who takes AI agents from prototype to production in regulated healthcare workflows. Joon is Actava.ai's first forward deployed engineer, building and deploying agents across prior authorization, care management, and payer operations. Over 13 years at Salesforce, he helped build three generations of its conversational AI, from NLU-driven chatbots through generative copilots to autonomous agents. As a lead developer on Agentforce, he built core backend services for agent execution, including the graph runtime that adds deterministic control to LLM agents, with a focus on the reliability and security enterprise deployments require. In Salesforce AI Research, he helped lead a small team building AI incubation projects for enterprise customers including Kaiser Permanente, RBC Royal Bank, Equinox, and Adecco, where he ran head-to-head evaluations of agentic reasoning approaches, LLMs, embedding models, rerankers, and RAG architectures. His earlier Salesforce work spanned search relevance, Knowledge search features, and healthcare data models. Before Salesforce, he was an early engineer at Fitbit. He holds a B.A. in Applied Mathematics and Computer Science from UC Berkeley.
