Hi, this is Elias from Miami. Excited about your search for a smart contract developer to help build a decentralized exchange on Ethereum. I’ve spent years writing secure, gas-optimized Solidity contracts and have hands-on experience with DeFi protocols — from AMMs to yield farming and liquidity mining. I understand the importance of security audits, upgradeable contracts, and gas efficiency, especially in fast-moving startup environments. Collaboration and rapid iteration are my daily drivers. Would love to bring my Solidity expertise and DeFi passion to your team and help build something that pushes the ecosystem forward. Quick questions: Q1: Are you focusing on an AMM-style DEX or order-book model? Q2: Is there a preferred framework (Hardhat, Truffle, Foundry) for your contracts? Q3: Will this include governance tokens or just core trading features at first? Q4: How big is the dev team now and what’s your expected sprint cadence? Looking forward to hearing from you. Regards.
