What I do

Ten Years Under That One Idea

The brain layer is what I'm building right now. It sits on ten years of everything else.

AI Agents in Production

Not demos. Agents with paying users, error rates I can quote, and architecture decisions I reversed in public. I built VTEX's Copilot with RAG and multi-agent orchestration, and I've run two of my own in production since.

Products People Pay For

Appcitas has been live since 2015. WalioAI is my 2026 bet. Real customers, two currencies, two markets, and pricing that had to survive contact with a Colombian small business.

Backend That Survives

Delivery routing for 400+ stores, checkout that survives Black Friday, and a production AI stack that costs under two dollars a month. None of it matters if it pages you at 3am.

Stuff That's Actually Live

Products people pay for. Not prototypes.

25,232 leads

WalioAI

My 2026 bet. 25,232 leads captured so far. Your AI agent responds, qualifies, and emails you when they're ready to close. Pay per qualified lead.
