Full-Stack Blockchain Developer | React.js | Node.js | Solidity | Smart Contracts Hi! I'm a passionate and results-driven full-stack developer with strong hands on experience building powerful web applications and decentralized solutions. I specialize in React.js and Node.js for crafting responsive frontends and scalable backends, along with Solidity and Ethereum smart contract development for blockchain-powered platforms. Whether it's dApps, DeFi platforms, token creation (ERC20/ERC721), NFT marketplaces, or web3 integrations — I bring both the technical expertise and strategic mindset to deliver clean, secure, and production-ready code. I focus on writing clean, auditable smart contracts, optimizing gas usage, and following security best practices like reentrancy guards and contract upgradability. Whether you're looking to bring your Web3 idea to life or need someone to scale your existing dApp, I'm here to deliver quality, reliability, and speed — always aligned with your business goals. Let’s connect and make your vision a reality!
