    Hi! I'm a passionate developer with hands-on experience in building Web3 applications, smart contracts, and full-stack blockchain systems. I'm excited about contributing to decentralized technologies and can help drive your PoC components to production-ready systems.

    Hello!

    Thank you for your request and the cool project! I am a developer with experience in creating Web3/DEX solutions: cross-chain token exchange, MetaMask/WalletConnect integration, smart contracts in Solidity. I have worked with React, TypeScript, ethers.js for the frontend and Node.js, NestJS for the backend, as well as conducted smart contract audits. I have implemented DEX prototypes with liquidity pools, translated PoC into production-ready solutions.

    Ready to take on refining the PoC, developing features, or conducting audits, and can suggest stack optimizations. I can show examples of my work: [link to DEX or Web3 project/repository, if available].

    Write to discuss details and tasks! Have a great day!
