Nguyễn Nhật Long - Senior Frontend Engineer

I'm a Senior Frontend Engineer and Frontend Team Leader with 6+ years of experience building high-performance web applications. Currently, I lead the frontend team at Nami Exchange, where I architect and develop the trading platform ecosystem serving hundreds of thousands of users in real-time.At Nami, I've architected 10+ products: Futures Trading with 125x leverage and real-time orderbook, Copy Trading, DeFi Insurance with Web3/smart contract integration, and a Telegram Mini-App, one of the first complex financial apps within Telegram's ecosystem. Each product handles real-time data through WebSocket connections processing 10+ market updates/second without UI lag.Beyond the web, I built the Nami Exchange mobile app using React Native with full TradingView and KlineChart integration, achieving 80% code reuse between web and mobile. I also developed native home screen widgets for iOS (WidgetKit) and Android to display real-time market data.Deep expertise in React, Next.js, Vue.js, TypeScript, and React Native. From Web to Mobile to Telegram Mini-Apps to Web3, I ship across every platform.The results speak for themselves: 45% faster load times through code splitting and bundle optimization, 35% increase in mobile engagement through responsive trading interfaces, 50% faster feature delivery through a standardized component library, and 40% fewer production bugs through coding standards and review processes I established.As a leader, I define architecture, establish coding standards, review solutions, and mentor developers. I deliver production apps with both React/Next.js and Vue.js/Nuxt.js. In fintech, every millisecond of lag can cost users real money, and that's the standard I build to.
