About Cristiano

I build production AI agent systems that actually ship — not prototypes. Currently running AION, a multi-agent platform with 71 AI agents live in production, architected with LangGraph and DeepSeek-V4-Flash, handling everything from regulatory compliance automation to an AI voice receptionist product used by small businesses across the US, UK, Canada, and Australia.

What I bring: 10+ years managing large-scale multinational projects (Brazil, Argentina, Colombia, Mexico, Chile, USA) with measurable financial results — a foundation I now apply directly to AI product development. I don't just write code; I own the full cycle from market validation to production deployment.

Typical projects I take on:

Multi-agent system architecture and orchestration (LangGraph, custom agent frameworks)
LLM integration and agent design for real business workflows
Backend architecture for AI products (FastAPI, PostgreSQL/Supabase)
Payment and third-party integrations (Stripe, Vapi.ai voice/telephony, agent-to-agent protocols)
End-to-end delivery: from idea validation to a working, deployed system your team can actually use
If you need an AI agent built and shipped — not just a proof of concept that never leaves a notebook — let's talk.
