About this gig

Not another chatbot, a real AI agent that uses tools, makes decisions, and gets work done.I'm a Toptal-vetted AI Agent Engineer. I build autonomous and semi-autonomous agents that plan, call tools/APIs, search your data, and complete multi-step workflows, the kind of systems most freelancers can't actually ship.What I build:- Agents that use tools: search, code execution, database queries, API calls, browsing- LangGraph multi-agent systems with supervisors, routing, and human-in-the-loop approval- MCP servers (Model Context Protocol) so your agent plugs into Claude/Cursor/any MCP client- Memory, RAG grounding, and guardrails so the agent stays reliable and on-task- Evals plus testing so you know it works before it touches productionProof: I've built a live LangGraph deepagents resume-screening system, a signal-monitoring executive-summary agent, and a self-healing multi-tenant automation engine.This is advanced work, message me with your use case and I'll tell you honestly if an agent is the right tool and how I'd build it.

Toptal-vetted AI engineer (top 3%) — I build AI agents, chatbots, automations, and voice assistants that actually work in production, not just demos. I've shipped AI agents with LangChain, LangGraph & MCP, RAG chatbots grounded on real data with citations, a live multilingual voice assistant, and Make.com/n8n automations with self-healing error handling. Stack: Python, LangChain/LangGraph, FastAPI, Next.js, OpenAI & Claude, pgvector/Supabase, Make.com, n8n. Message me before you order — tell me what you're building and I'll give you a straight answer on how I'd approach it.
