Transform Demo App(Interpreter Platform) Into Production -- 2

My proof-of-concept already handles basic user login, simple content display and form submission, plus a few extras I bolted on for internal testing—call simulation and rudimentary data-metrics screens. Now I need this prototype hardened and expanded into a production-ready web application.

Where we start
• Existing codebase with the features above, running in a staging environment you’ll get access to.
• Clean UI/UX; no heavy refactor is required, but polish is always welcome.

What has to be added
1. Advanced user management with five roles: Admin, Editor, Viewer, Client and Employee. Each role must have clearly scoped CRUD permissions that can be adjusted later through an admin panel.
2. Real-time notifications—think WebSocket or a comparable solution—to broadcast system events instantly to the front-end.
3. Enhanced data analytics: aggregate, chart and filter the metrics already captured, then expose them in a dashboard.
4. WebRTC integration must rely on a free STUN server so users can keep making call simulations without paid third-party services.
5. Node.js for backend

Deployment expectations
• Secure, production-grade build (HTTPS, sanitised inputs, robust auth).
• Fully documented source code and setup guide so I can re-deploy.
• All new features covered by basic unit or integration tests.
• Live demo URL for final review.

If you’ve taken a demo to full release before and feel comfortable with real-time tech such as WebRTC, let’s talk deliverables and timeline.
