• Implement client-side caching and state management using React Hooks

• Introduce dynamic styling solutions (CSS variables, TailwindCSS, etc.)

• Add features such as Dark Mode, internationalization, and localization

• Create and maintain unit, integration, and E2E test structures

• Implement SSR using Next.js

• Host and deploy React applications across multi-region cloud environments

• Integrate with REST APIs and debug production issues in Unix-based systems

• Evaluate emerging UI frameworks and contribute to the evolution of component libraries

• Use Storybook, monorepos, and modern tooling to scale frontend development
