    • Lead the delivery of multi-brand, multi-tenant app features that support MG, MobileHelp, and MedScope ecosystems.
    • Support migration of legacy portals/apps into the unified platform.
  • Innovation

    • Drive personalized engagement features leveraging AI/ML and the Behavioral Digital Twin model.
    • Participate in patent filings and thought leadership around digital healthcare experiences.

    • Mastery of React.js/React Native, JavaScript/TypeScript, and modern frontend frameworks.
    • Experience with Flutter or hybrid frameworks for cross-platform delivery.
    • Strong understanding of CMS integration, micro frontends, and modular app design.
    • Expertise in responsive design, accessibility (WCAG 2.1+), and performance optimization.
  • Architecture & Systems
    • Experience designing for multi-brand, multi-tenant platforms.
    • Familiarity with Azure cloud ecosystem (App Services, Static Web Apps, Blob/CDN).
