I will build a langchain rag ai agent with vector database and apis

Need a custom LangChain RAG AI agent that can answer from your documents, business data, website, PDFs, or knowledge base?

I will build a custom LangChain or LangChain.js RAG AI agent with vector database integration, accurate retrieval, source citations, and API-connected workflows.

This is not a basic chatbot script. I build custom-coded AI systems that can retrieve relevant context from your data, generate accurate answers, and connect with your app, dashboard, CRM, database, or business tools.

I can build:

• LangChain RAG AI agent
• Document Q&A chatbot
• PDF or website-trained assistant
• Knowledge-base AI agent
• AI agent with tool calling
• OpenAI, Claude, or Gemini integration
• Vector database setup with Pinecone, Supabase Vector, Qdrant, or Chroma
• Next.js, React, Node.js, and API-based AI apps

You will receive clean source code, RAG pipeline setup, embeddings, vector search, AI chat interface, prompt optimization, testing, documentation, and deployment support depending on your package.

Message me before ordering so I can suggest the best architecture for your project.
