Joao Renato Maximiano Menezes

I’m a Web3 Game Developer with over 4 years of hands-on experience building blockchain-integrated games, smart contracts, and multichain applications. My focus is on delivering immersive, decentralized gaming experiences powered by Solidity, React.js, ethers.js, and scalable backend infrastructure.

I specialize in full-stack dApp development, from architecting ERC-20/721/1155 smart contracts to integrating wallet logins (MetaMask, WalletConnect) and handling staking, rewards, and NFT minting logic. I’ve deployed contracts and dApps across Ethereum, Polygon, and BNB, and have extensive experience with cross-chain architecture, IPFS-based asset storage, and secure transaction flows.

On the frontend, I use React.js and Tailwind CSS to create fast, interactive user interfaces connected directly to the blockchain via ethers.js. I’ve led the development of real-time token dashboards, staking UIs, NFT mint/reveal flows, and on-chain/off-chain game logic coordination. I’ve also worked closely with designers, 3D artists, and backend teams to align smart contract logic with gameplay mechanics and token utility.

I follow best practices in blockchain security, including access control (Ownable, Roles), reentrancy protection, gas optimization, and test-driven development using Hardhat. I also write full unit/integration test coverage for contracts and simulate real attack surfaces before deployment.

Whether you're launching a full Play-to-Earn game, adding NFTs to an existing product, or need a reliable smart contract developer for a multichain metaverse, I bring speed, structure, and deep technical experience to every project. I work independently, communicate proactively, and deliver production-ready code with clear documentation and clean git history.

Let’s build the next great Web3 experience together.
