Overview
Developed a comprehensive remote management solution for TouchIT Interactive Flat Panels (IFPDs) that combines a client-side Android application with a web-based control portal. Built entirely solo, this platform enables IT administrators to centrally manage, monitor, and control multiple interactive displays from anywhere with an internet connection. The system addresses the critical need for scalable device management in educational institutions and corporate environments where dozens or hundreds of interactive panels require coordinated administration and support.
Key Responsibilities & Achievements
- Built centralized management for thousands of global LED displays
- Implemented real-time device monitoring and health tracking
- Created mass deployment system for software updates
- Developed remote troubleshooting and diagnostic capabilities
- Achieved scalable architecture supporting global installations
Technical Implementation
The platform leverages a sophisticated real-time architecture combining Node.js backend with React frontend, deployed on Digital Ocean infrastructure with MongoDB for persistent data storage. The system utilizes dual real-time communication channels: Pusher for instant notifications and Socket.io for bidirectional device communication and control signals. The Kotlin Android service application runs as a background utility on TouchIT LED displays, maintaining persistent connections to the management portal through secure pairing IDs. Remote control functionality represents a key technical innovation, utilizing WebRTC technology through OpenVidu or Agora (based on available credits) to stream LED display screens in real-time to the web portal.
Impact & Results
- Revolutionized IT support efficiency by enabling remote troubleshooting and control without physical presence at device locations
- Reduced operational overhead through centralized management of multiple interactive displays from a single web interface
