About this gig
Multi-AI Agent Systems CrewAI, LangGraph, n8n, MCP & Claude API
Need agents that actually work together planning, delegating, and executing tasks without you babysitting every step? I build multi-agent systems using CrewAI, LangGraph, AutoGen, n8n, and the Claude API. Each system is scoped, built, and delivered ready to run.
What I set up:
- CrewAI agent crews with custom roles and task handoffs
- LangGraph state machines for complex branching logic
- n8n workflows that trigger and route agents automatically
- MCP server integration for tool use and external data access
- Claude API and OpenAI orchestration inside agent pipelines
- Memory, RAG, and tool-calling across agent teams
- AutoGen multi-agent conversations and execution loops
- Agent connections to Slack, Notion, Zoho CRM, Airtable, Google Workspace, and custom APIs
I work across cloud-hosted and local setups. You get working code, documentation, and a handoff walkthrough so you or your team can extend it.
Message me before ordering, projects vary and I want to scope yours properly before we start.

I build AI agent systems, automation workflows, and custom integrations for businesses that want to stop doing things manually.
My stack: CrewAI, LangGraph, AutoGen, n8n, Claude API, Vapi, Retell AI, MCP servers, Make.com, Zapier, Zoho CRM, Wix headless, and FlutterFlow.
I work on multi-agent pipelines, voice AI systems, CRM automation, no-code/low-code builds, and API integrations. Most of my clients come with a process they want automated or a system they want built. I scope it, build it, and hand it off with documentation.
FAQ
What frameworks do you use?
CrewAI, LangGraph, AutoGen, n8n, and Claude API. I pick the right one based on your use case sequential tasks, parallel agents, or event-driven workflows.
What's MCP and do I need it?
MCP (Model Context Protocol) lets agents use external tools like databases, APIs, and file systems. Recommended for any system that needs real-world data access.
Can agents connect to my existing tools?
Yes. I integrate with Slack, Notion, Zoho CRM, Google Workspace, Airtable, and custom REST APIs.
Do you use Claude or OpenAI?
Both. I default to Claude API for reasoning-heavy agents and can mix models in one system.
Will I be able to manage the system after delivery?
Yes. I provide documentation and a short walkthrough so you can run, monitor, and update it.
What's the difference between CrewAI and LangGraph?
CrewAI is role-based and faster to set up for task delegation. LangGraph gives finer control over state and branching logic. I'll recommend the right one for your project.
Can agents run on a schedule or trigger automatically?
Yes. I wire agents to n8n or webhook triggers so they run on a schedule or respond to events.
Do you build RAG agents?
Yes, agents with retrieval-augmented generation, connected to your documents, database, or knowledge base.
What do you need from me to start?
A description of the task the agents should perform, what tools or data sources they need, and your preferred platform (cloud, local, or n8n-hosted).
Can you hand this off to my dev team?
Yes. I deliver clean, documented code with a setup guide so your team can extend it.
