SUMMARY
Built and maintained a Web3 app for smart contract interaction via MetaMask, including transaction signing
and on-chain data fetching with ethers.js. Designed a scalable Vue 3 (Composition API) + TypeScript
architecture with clean business logic separation.Integrated REST APIs with Axios, handling auth, token
management, and error handling. Implemented DeFi logic (BigInt, token decimals, health factors, liquidation
flows) ensuring accurate financial calculations. Used GitHub Copilot to speed up development, improve
productivity, and assist with debugging and code generation.
