I work deeply with blockchain infrastructure, ensuring applications behave reliably under real user conditions. The projects I’ve worked on include: - NFT platforms as an experienced nft developer: landing-based apps, SPA and multi-page applications, NFT marketplaces, hybrid exchange systems, and Uniswap forks - Smart contract integrations as a Blockchain Developer: contract interaction using web3 and ethers libraries, handling transactions, events, and contract state as a smart contract engineer - Wallet integrations as a Web3 Developer: Metamask connections, custom Web3 context implementations, and secure interaction flows - Backend systems as a Full Stack Developer: building services with Node.js and TypeScript, working with MongoDB (Mongoose), PostgreSQL (Supabase), and Prisma for NFT data and application logic - Blockchain data querying as a Blockchain Developer: using Apollo Client with Uniswap subgraphs to fetch and process on-chain data efficiently - Gas optimization as a Web3 Developer: creating services that fetch gas price predictions and apply them to outgoing transactions - Exchange integrations as a Full Stack Developer: working with Binance API, order creation, and financial workflows As a Web3 Developer and Blockchain Developer, I have strong experience working with solidity, including creating ERC20 mintable tokens and handling contract deployment pipelines with Hardhat.
