Real-Time Web App Development

I need a full-stack web-based software application that can demonstrate reliable, low-latency real-time updates. The specific domain and feature set are ready to share once we start, but the core requirement is that data pushed from the server must appear instantly on the client without a page refresh.

The build has to be coded from scratch, kept clean, and thoroughly commented so I can present and defend every line during my final-year review at VIT Chennai. As part of the hand-off, walk me through the overall architecture, the data flow that powers the real-time layer, and any third-party services or libraries you integrate.

You will also guide me through local and production deployment, supply a concise testing plan, and stay available for minor tweaks until my submission date. I am flexible on tools—whether you prefer WebSockets, Server-Sent Events, or a managed service such as Firebase/Firestore—so long as the real-time behaviour is seamless and the stack remains easy for me to showcase.

Deliverables
• Complete, well-documented source code in a public or private repository
• Written explanation of architecture, setup instructions, and deployment steps
• Short video or live walk-through session clarifying implementation choices
• Assistance with testing, bug fixes, and small iterations up to final submission

Once these points are met and I have everything running smoothly on my machine and the demo server, the project will be considered complete.
