Integrate real-time WebSocket data into live UI updates — order books, price tickers, trade feeds, and candlestick charts

Implement transaction signing and submission for swap, mint, and order flows via Viem, replacing paper trading placeholders with real on-chain execution

Own the wallet connection experience across 8+ providers using EIP-6963, and collaborate with the smart contract developer on ABI integration and on-chain event handling

Connect frontend to backend REST APIs for market data, order management, and swap quotes, ensuring consistent data contracts across the stack

Write clean, well-typed TypeScript with a focus on component reusability, performance, and maintainability

Solid experience consuming REST APIs and WebSocket streams for real-time data rendering

Hands-on experience with Tailwind CSS and responsive, accessible UI design

Familiarity with Web3 frontend integration — wallet connection, transaction signing, and contract interaction via Viem or Ethers.js

Experience with charting libraries such as lightweight-charts, klinecharts, or TradingView

Comfortable working in a monorepo structure and collaborating across frontend, backend, and smart contract teams
