Project Overview: We are an outdoor advertising company installing 23-inch and 28-inch high-brightness LCD screens on delivery scooters. We already have the UI/UX designs ready in Figma. We need a pure development partner to build the backend (CMS) and frontend dashboard to manage ads across our scooter fleet. Key Responsibilities: Frontend: Develop a pixel-perfect web dashboard based on our Figma designs (React.js or Vue.js preferred). Backend: Build a robust CMS (Node.js/Python/PHP) to upload, schedule, and manage video/image ads. Hardware Integration: Create a system to "push" content to remote Android-based media players over 4G/LTE. Remote Monitoring: Real-time tracking of screen status (Online/Offline) and GPS location. Performance: Ensure "Offline Playback" so ads continue running if the scooter loses network. Technical Requirements: Experience with MERN Stack (MongoDB, Express, React, Node.js) or similar. Familiarity with Digital Signage APIs or remote device management. Understanding of Socket.io or WebSockets for real-time communication between the server and screens. Knowledge of AWS/Google Cloud for media storage and hosting. Please include examples of similar work in your bids.
