Cali, Colombia
Builder working at the intersection of AI agents and Ethereum.
Currently building Darwin Agents: a population of autonomous marketing agents that compete for budget, reproduce when profitable and shut down when they lose money. Each agent holds its own HD wallet and signs its own on-chain spend() call, with four independent spending caps enforced by the AgentTreasury contract rather than by instructions to a model.
Stack: Solidity/Foundry, TypeScript, Next.js, viem.
Deployed and verified on HashKey Chain Testnet (chainId 133).
