Your Responsibilities

• Bring high‑fidelity designs to life with pixel‑perfect, responsive, and accessible UI implementation.

• Build scalable, reusable UI components and maintain a cohesive design system.
• Ensure cross‑browser compatibility, including required polyfills and fallbacks.
• Drive performance excellence through:
  • Smart asset loading (lazy loading)
  • Code splitting and optimized bundling
  • Dynamic imports
  • Bundle size analysis and reduction
  • Lighthouse & Core Web Vitals improvements
• Apply appropriate rendering or delivery techniques (e.g., SSR/SSG/ISR when applicable).
• Implement and maintain WCAG‑compliant accessibility standards.
• Integrate front-end applications with REST APIs using clean, maintainable JavaScript logic.
• Write robust documentation, clean code, and enforce quality through best practices.
