Today’s AI frameworks excel at building prototypes. But when autonomous agents need to run continuously in production, developers are left on their own. This talk takes a first-principles approach to agentic systems. Instead of chasing frameworks that will be obsolete tomorrow, we focus on the enduring patterns and principles that outlast any particular implementation. You’ll walk away with a systems engineering mindset for agentic applications—one that helps you move from fragile prototypes to reliable, scalable, and long-lived production systems.
