Hello! I'm Alex, a full stack blockchain developer with expertise in smart contract development, bot creation, and front-end integration. Here are some of the skills I bring to the table: Bot Development I’ve built custom bots to monitor DeFi positions, track NFT ownership, and automate transactions across EVM-compatible chains. Smart Contract Development I’ve written, tested, and deployed smart contracts for DeFi protocols, NFT projects, and custom dApps. NFT Projects I've successfully launched multiple NFT projects, handling everything from metadata creation to deployment.​ Front-End Integration I am experienced with ethers/web3.js, and can seamlessly connect smart contracts with front-ends. Technical Consulting I’ve helped dev teams troubleshoot complex issues and keep projects moving efficiently. My goal is to understand your problem and work with you to deliver a clean, effective solution. Looking forward to working together, Alex
