Since childhood, I've been into computers. I've programmed for over seven years and started with Bitcoin and blockchain in 2013. Now, I mostly work on Web3, especially smart contracts and blockchain backend development. I've made many ERC-20 tokens and contracts for different uses, including for DeFi protocols. I made the first Portuguese Solidity course on YouTube, covering basics to advanced topics. With some other developers, we started the web3dev community. Our goal is to help Portuguese-speaking developers learn more.
