AI Agent Developer — LangChain · n8n · OpenAI · RAG Pipelines (Fixed-Price Project)

We need an experienced AI agent developer to build a custom autonomous agent that can reason, use tools, and complete multi-step tasks on our behalf. This is a defined, fixed-price project with clear deliverables — we want someone who has shipped production AI agents before, not someone learning on our budget. ━━ PROJECT SCOPE ━━ → Design and build a multi-step AI agent using LangChain, LangGraph, or CrewAI → Agent must use tool-calling to interact with external APIs and our internal database → Implement RAG (Retrieval-Augmented Generation) using our document corpus (PDF + web sources) → Vector store setup using Pinecone or Qdrant for semantic search → Memory management — short-term conversation memory + long-term persistent context → Deploy the agent via n8n or a lightweight API endpoint (FastAPI / Node.js) → Full documentation + handover call
