Anyone can spin up an AI agent in five lines. Would you give that agent a refund button? In this demo-driven talk I build a customer support bot with LangGraph, the framework behind agents at Klarna, Uber, and J.P. Morgan, to show why control matters in production. Instead of letting the model improvise, I lay the bot out as a graph: it answers the easy questions on its own, pauses for human approval before anything irreversible like a refund, and resumes where it stopped after a crash. Then I ship it to AWS. Claude on Amazon Bedrock runs the model, Amazon Bedrock AgentCore hosts the bot, and the Agent Toolkit for AWS handles model access, IAM, and deployment from inside the coding agent. You'll leave knowing how to start with LangGraph, how to run it on AWS without a platform team, and when a graph beats a free-roaming bot.
