🚀 Senior Full-Stack & Blockchain Developer | Smart Contracts | Web3 dApps

I help businesses build scalable web apps and blockchain solutions—from powerful smart contracts to sleek Web3 frontends.

What I deliver:

âś… Smart contracts (ERC-20, ERC-721, DeFi, staking, NFT)

âś… Web3 integrations (Metamask, WalletConnect, Ethers.js)

âś… Full-stack apps (React, Next.js, Node.js, APIs, databases)

âś… Secure, optimized, and future-proof code

With years of experience across frontend, backend, and blockchain, I bring the skills to take your project from idea to launch—fast, reliable, and done right.

💡 Let’s build your next big thing in Web2 or Web3.
