Make a single-page e-commerce app that works on all devices and has a product catalog, filters, a cart, and a checkout. Use Angular and RxJS for a reactive UI and NgRx for state (cart, wishlist, and auth). Add a secure JWT login and an admin panel for managing inventory and orders based on roles. Use a Node/Express REST API and improve it with lazy loading and route preloading.

Make a helpdesk portal that lets people buy tickets, chat live, and assign agents. Use Firebase Auth and Firestore to handle authentication, presence, and real-time data streams. Send as a PWA with offline caching, background syncing, and push notifications. Add dashboards for SLAs, agent productivity, and reports that can be exported.

Make a Kanban-style dashboard for tasks, sprints, and projects that you can drag and drop. Use charting libraries and reusable parts to show velocity and burndown. Use WebSockets or Firebase to let people see comments and status updates in real time. Set up form validation, guards, interceptors, and build configurations that are ready for CI/CD.
