• Familiar with modern frontend frameworks (React, Vue, Angular), advanced UI engineering patterns, and CSS libraries like Bootstrap or Tailwind CSS.
• Advanced experience with complex state management libraries (e.g., Redux, Vuex, MobX) and architectural design of large-scale application state.
• Proven track record of optimizing frontend performance and web vitals at scale, including experience with server-side rendering (SSR), edge, or hybrid rendering architectures.
