Brazilian engineer, Lisbon-based. 14 years shipping.
I'm a Senior AI Fullstack Engineer with 14 years of experience building scalable applications across web3, fintech, and e-commerce. 4+ years deep in Web3 / Crypto, 2+ years building AI developer tools. Based in Lisbon, work worldwide.
Built 10+ AI agents for DeFi protocols across Solana, EVM, SUI, NEAR, and Cardano. Creator of Ralph Starter (AI coding orchestrator) and AEO.js (answer-engine optimisation). Both ship with 100+ daily npm downloads.
Most recently at MultiVM Labs, building Quantum, an L1 blockchain. Before that, four years on NEAR + EVM at Bitte Protocol: wallet, marketplace, trading agents, cross-chain SDKs. Earlier: lead frontend on Itaú's developer portal (the face of Open Banking at the largest bank in Latin America), Grover, and Brazilian agency work for Nike, Samsung, Centauro, Under Armour.
On the AEO side I also take on AEO engagements: fixed-scope projects that end with a before/after score report from check.aeojs.org (2,259 unique sites scanned and counting).
I care about the seams: how spec becomes code, how research becomes a product, how a UI feels when an agent owns half of it. Selectively available for AI tooling, agents, and Web3 work.
