Rafael Pierre guides participants through the complete lifecycle of building production-ready agentic AI systems for enterprise banking. Drawing from a live pilot deployment using OpenAI Agents SDK and Phoenix Arize, this workshop demystifies multi-agent orchestration, observability strategies, and deployment patterns. Attendees will architect a conversational loan application system, implement agent coordination, and establish monitoring frameworks that satisfy enterprise requirements. This technical session bridges the gap between proof-of-concept demos and scalable production systems through real-world banking use cases.
