• Integrating AI Capabilities : Explore and incorporate LLM APIs (OpenAI, Claude, open-source models) and frameworks (e.g., LangChain) for sophisticated AI interactions with memory, planning, and tools.
• Designing Data Flows : Use graph databases (e.g., Neo4j) to structure information for enhanced AI reasoning.
• Building Adaptive AI Systems : Develop systems that combine generative AI with real user data to create personalized experiences, using Python for AI integrations.
