    "description": "A digital signage content management and display platform combining\nReact for the web-based content designer and Electron for the kiosk\ndisplay application running on embedded PCs or Raspberry Pi devices.\nWebSocket connections via Socket.IO push real-time content updates,\nscheduling changes, and emergency overrides to displays without polling.\nRedis manages display state and pub/sub channels for fleet-wide content\nsynchronization. S3 stores media assets (images, videos, HTML widgets)\nwith local caching on display devices for offline resilience. Node.js\norchestrates the content scheduling engine. Designed for digital signage\ncompanies managing thousands of screens across retail, hospitality,\nand corporate environments. The tradeoff is device fleet management\ncomplexity and ensuring reliable content playback during network outages.\n",
