AI engineering: RAG and LLM systems in production

I take LLM features from prototype to production. Multi-agent systems with LangGraph, hybrid RAG with source grounding, plus evaluation and observability. The entry point is the LLM readiness check.

What's in the work

Multi-agent systems with LangGraph
Hybrid RAG with source grounding
Evaluation and observability (Langfuse, RAGAS)
MCP servers when the model needs tools
Hook into the existing app without rebuilding it
