1) Define reference architectures for GenAI systems: RAG, agentic orchestration, tool/function calling, multi-step reasoning workflows, memory patterns, and context strategies.

• Define reference architectures for GenAI systems including RAG, agentic orchestration, tool/function calling, multi-step reasoning workflows, memory patterns, and context strategies.
• Design multi-tenant and enterprise-scale GenAI platforms with clear separation of concerns: UI, orchestration, retrieval, inference, evaluation, and observability.
• Select model strategies: hosted LLMs, open-weight models, fine-tuning vs. prompt/RAG, latency and cost tradeoffs, and deployment patterns.

2) Agentic AI Orchestration & Tooling

• Architect agent systems (single/multi-agent) including:
• Tool use patterns (APIs, databases, search, workflow engines)
• Guardrails to prevent unsafe tool actions and hallucinated commands
• B...
