I will build a rag ai agent with langchain langgraph and fastapi

Need a reliable RAG system or AI agent instead of a basic chatbot demo? I will build a practical LLM application using LangChain, LangGraph, FastAPI, vector databases, and your preferred model provider.

Possible deliverables include:

Document ingestion, chunking, embeddings, and retrieval

RAG chat with citations and source references

Tool calling and external API integrations

Multi-step LangGraph agent workflows

Memory, guardrails, logging, and evaluation

REST APIs, simple web interfaces, and Docker deployment

I can work with OpenAI, Anthropic, Gemini, Llama, pgvector, Pinecone, Qdrant, Weaviate, or another suitable stack.

Please contact me before ordering so I can review your data sources, integrations, accuracy expectations, and deployment environment. Model usage, cloud, and third-party subscription fees are not included.
