I will build ai agents and multi agent workflows with langgraph and n8n


About this gig
I build AI agents that do real work inside a business: they read requests, use your tools and APIs, and complete tasks instead of just chatting.
Recent work: POS Agent, a live multi-agent system that runs point-of-sale and accounting through WhatsApp (LangGraph, OpenAI, MCP, FastAPI), and a WhatsApp expense assistant built with n8n and Claude.
What I can build for you
- AI agents with tool calling, memory and API actions
- Multi-agent workflows with LangGraph, CrewAI or AutoGen
- n8n automations powered by OpenAI, Claude or Gemini
- Agents connected to WhatsApp, email, CRMs, databases and your APIs
- RAG so the agent answers from your own documents
How I work
- We map the task, the tools the agent needs and its limits
- I build and test the agent on real examples from your workflow
- I deploy it (Docker, your server or n8n) and hand over documentation
With 6+ years of full stack engineering, I also build what sits around the agent: backend, database, dashboard and deployment.
Not sure which package fits? Message me with your workflow and I'll suggest the simplest setup that works.

FAQ
Which AI models do you support?
OpenAI (GPT models), Anthropic Claude and Google Gemini. I choose the model based on your task, budget and response speed.
Can you build multi-agent systems?
Yes. I build multi-agent systems with LangGraph, CrewAI or AutoGen, including routing, memory, guardrails and tool integrations. My POS Agent project uses separate agents for accounting, inventory and sales, coordinated through WhatsApp.
Can you automate my business processes?
Yes. Describe the process step by step and I will show where an AI agent or n8n workflow can take it over, connected to your APIs, CRM, email, WhatsApp or database.
Do you deploy the agent and hand over the code?
Yes. I can deploy it with Docker on your server or cloud, or run it in your n8n instance. You get the code and documentation so your team can maintain it.
What do you need from me to start?
A short description of the task, a few real examples of inputs and expected results, and access to the tools or APIs the agent should use. I confirm the scope and the right package before we start.
