- Implement Progressive Web App (PWA) capabilities, including service workers, web app manifests, offline-first caching strategies, push notifications, and installability, ensuring reliable performance across devices and network conditions.
- Build and maintain RESTful APIs in Node.js that serve both web and mobile-optimized clients, design endpoints with mobile payload efficiency and performance in mind.
- Design and maintain MongoDB collections, schemas, and queries supporting custom application data models, while applying NoSQL data modeling best practices.
- Build reusable React components with state management (Redux or Context API), responsive layouts, and touch-friendly interactions suited for mobile and tablet users.
- Integrate frontend applications with REST APIs and third-party enterprise services, including API authentication, error states, and offline fallback.
- Apply the full SDLC across the Mobile Apps Program area, including design, development, testing, deployment, and production support.
