  • 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.

  • Strong proficiency in React, including component design, hooks, state management (Redux or Context API), and building responsive, mobile-optimized interfaces with modern JavaScript (ES6+).
  • Hands-on experience implementing PWA features: service workers, web app manifest, offline caching strategies (Cache API, Workbox), push notifications, and app installability.
  • Experience designing and delivering web applications that perform well on mobile and tablet devices, such as touch interactions, responsive layouts, performance optimization for mobile networks, and testing across device sizes.
  • Working experience with MongoDB, including document design, CRUD operations, indexing, and aggregation pipelines.
