Onchain analyst · AI & blockchain builder
Juan Sebastian Garcia
For over a year I have been working on AI, blockchain and onchain analysis projects. The main one is Criollo, an AI agent that helps animal rescue foundations document the whole care process, recording every health event of each animal that is waiting for a forever home.
I build in Miami, and I want more people to learn new technologies and take the risk of building solutions to everyday problems.
Featured project
Criollo
An AI agent for animal rescue foundations. Each intake, vaccination, treatment, transfer and adoption becomes a dated care event, so the full history of an animal can be shown to adopters, donors and partners.
Privacy comes first: animals, shelters and operators are hashed before they are stored, and the design keeps personal data off the chain.
- Telegram agent built on ElizaOS and the Anthropic Claude API.
- Care event logger with five event types and 32 categories, backed by PostgreSQL.
- Verifiable Care Receipt (VCR) design, with a live mint on Solana Devnet and attestations planned on Base.
- Finalist at the WayLearn x Solana Foundation Hackathon. Now in incubation.
- Animal Health Passport demo built at the eMerge AI Hackathon 2026 in Miami.

An invented record that shows the shape of the data. The animal appears only as a hash, never with a name, photo or owner details.
What I do
Onchain analysis
I read public blockchain data to see how money moves: wallet tracing, holder behavior, whale tracking, network activity and capital rotation. I completed a 65-hour onchain analytics program and use the same methods in my own market research.

I build agents that do real work: a Telegram agent for Criollo, and a WhatsApp and voice ordering agent for a restaurant that is still at pilot stage. I wire them to tools, memory and spreadsheets.

Projects deployed on Solana, Sui and Base. I build with an AI-assisted workflow and I am open about it: I design the system, review what the code does and test it before it ships.

I run Todo en Cadena, a Spanish-language community that explains crypto and onchain tools in plain words.
Speaking
Criptolatinfest 2026 · Maloka, Bogotá · August 28 · AI room
From collars to crops: how AI is rewriting the world of those of us building Web3 infrastructure in LATAM
A 35-minute talk on how small teams with limited resources can use AI for intelligence and automation, and Web3 for trust, ownership and verifiable rules. It follows two real cases, a livestock GPS collar company and a farmer who automated a 100-hectare farm with AI, and ends with Criollo, the animal rescue project I am building.
