  • Establish best practices for performance optimization, accessibility (WCAG), SEO, security, and responsive design.

2. Adobe Experience Manager (AEM) Expertise

  • Design and implement frontend architectures integrated with Adobe Experience Manager (AEM).
  • Work with AEM Sites, Core Components, editable templates, client libraries, and content fragments.
  • Integrate frontend applications with AEM Content Fragment APIs, GraphQL, and REST services.
  • Understand AEM as a Cloud Service, including deployment pipelines, caching, and CDN considerations.
  • Establish reusable AEM-compatible UI components and authoring-friendly design patterns.

3. Generative AI & Claude Integration

  • Demonstrate practical experience with Anthropic Claude and Claude Code for AI-assisted software engineering.
  • Use Claude to accelerate UI development, code generation, refactoring, debugging, and documentation.
  • Define AI-assisted engineering workflows across the frontend development lifecycle.

4. Engineering Excellence & DevOps

  • Define frontend CI/CD practices using GitHub Actions, Azure DevOps, Jenkins, or equivalent platforms.
  • Establish unit, integration, and end-to-end testing strategies using Jest, React Testing Library, Playwright, or Cypress.
  • Drive Core Web Vitals improvements, bundle optimization, caching, and rendering strategies.
  • Establish frontend code quality, security, and observability standards.
  • Collaborate with UX/UI designers, product owners, enterprise architects, and engineering teams.
