• Architected enterprise React/Next.js platform with micro-frontend patterns using module federation, hybrid rendering (SSR/ISR/CSR), achieving FCP less than 1.2s and LCP less than 2.1s on 3G networks.
• Engineered custom Webpack 5 config reducing bundle 40% (850KB→510KB gzipped) via aggressive code-splitting, tree-shaking optimization, dynamic imports with priority hints, and automated bundle analysis in CI blocking oversized PRs.
• Built design system with 60+ compound components using render props and custom hooks; integrated Storybook with Chromatic for visual regression testing across 12 breakpoints.
• Designed sophisticated state architecture combining Redux Toolkit with RTK Query for global state, React Query for server cache normalization, and Redis-backed SSR caching (92% hit ratio)—reduced API calls 60%.
• Built type-safe Redux Toolkit architecture with slice patterns, createAsyncThunk for side effects, and Reselect memoized selectors for WebSocket data—achieved virtualized rendering of 10K+ concurrent stock streams without jank.
• Established observability pipeline: Lighthouse CI blocking regressions, Sentry performance monitoring, RUM analytics tracking INP/CLS/TTFB—achieved 95+ Lighthouse scores via resource hints, critical CSS inlining, and CDN edge caching.
