Worked on the awslabs/amazon-bedrock-agentcore-samples repository to upgrade guardrails memory integration, focusing on improving memory handling and developer experience. Replaced a custom memory solution with the built-in AgentCoreMemorySessionManager, which streamlined session lifecycle management and reduced runtime fragility. Addressed stability and correctness by configuring memory modes and injecting existing memory IDs to prevent failures and resource duplication. Updated documentation and sample notebooks to reflect changes from Claude 3.7 Sonnet to Claude Haiku 4.5, ensuring clarity for end users. Leveraged AWS, Python, and full stack development skills to deliver a more robust and maintainable memory management workflow.
