About Alejandro
My current focus is on the Ethereum ecosystem, where I’ve been developing with Solidity, Hardhat, OpenZeppelin, and Ethers.js, while applying best practices for security, testing, and gas optimization. I’ve also explored DeFi protocols, NFT standards (ERC-20, ERC-721, ERC-1155), and smart contract architecture patterns.
With a solid background in JavaScript, TypeScript, Java, and databases like MySQL/MongoDB, I bring both backend and frontend expertise to blockchain projects. I’m actively contributing to my portfolio of Web3 applications and collaborating on open-source initiatives.
I’m legally authorized to work in both Spain and the US.
