Apr 2021 - Present • 5 yrs 5 mos

I specialize in Web3 wallet integration, connecting MetaMask, WalletConnect, Coinbase Wallet, and Trust Wallet directly into websites and decentralized applications (DApps). Using Web3.js and Ethers.js, I build secure wallet-connect login systems that support multiple blockchain networks including Ethereum, BNB Chain, and Polygon. My work covers wallet authentication, message signing, and transaction handling, tested across both desktop and mobile devices before delivery. I review each client's existing codebase and requirements closely before starting, so the integration fits cleanly into their site without breaking existing functionality. Every project is delivered with clear documentation and support through revisions until it works exactly as expected. My focus is on secure, reliable wallet connectivity — helping crypto platforms, NFT sites, and DApps give their users a smooth, trustworthy login experience.
