Project details
You will get a multi-agent AI system built with LangGraph — a team of AI agents that plan, call tools, check each other's work and handle complex workflows end to end.
I'm Volodymyr, AI Agent Developer with 89 delivered projects. My multi-agent systems run in production for SaaS, FinTech and LegalTech teams.
What you get:
• LangGraph supervisor + specialist sub-agents: retrieval, reasoning, tool calls, verification
• Connected to your stack: APIs, databases, RAG pipeline, MCP tools
• Guardrails, evals and monitoring — agents you can trust in production
• Source code, docs and a handoff walkthrough
BEFORE ORDERING — message me with a couple of lines about your workflow. I reply within a few hours and we'll confirm the scope and the right tier.
Complex orchestration or many integrations? The Premium tier covers a full agent team with deployment — or I'll send a custom offer.
Keywords: multi agent system, langgraph developer, agent orchestration, autonomous agents, ai agent development, crewai, supervisor agents, tool calling, openai, claude, python.
