Built a responsive, decentralized crypto exchange dApp on the Ethereum Sepolia testnet. Developed Solidity smart contracts with Remix for Testing and Hardhat for deployment, Alchemy for blockchain access into the Sepolia Testnet, and MetaMask for secure wallet integration.

Web3 (Ethers.js) enabled real-time wallet connection, token swaps. Followed DevOps practices for automated deployment using Netlify for hosting and Git/GitHub for version control.
