I need a bespoke content-management platform built specifically for digital-signage advertising. The system must let me upload, organise, schedule and remotely push images, videos and text-based ads to screens installed both indoors and outdoors. Core requirements • Web-based dashboard to manage campaigns, playlists and screen groups • Real-time or near-real-time content updates over the internet • Responsive playback app/player that runs on common media-player hardware (Windows, Android or similar) and pulls the assigned content automatically • User-level permissions so multiple advertisers can manage their own material without overlap • Basic reporting on what played and when, with export options I’m open to your recommended stack (Laravel, Node, Django, React, etc.) as long as it remains scalable and easy to maintain. Please outline: 1. Your proposed architecture and key tech choices 2. How you’ll handle offline fallback for screens that lose connection 3. Estimated timeline and milestone breakdown 4. Any relevant past projects or demos Once we agree on the scope, I’ll supply branding assets and any additional interface sketches needed to get started.
