Project Overview
SmartLife IoT is a cutting-edge smart home platform that seamlessly connects and manages millions of IoT devices worldwide. I architected the entire backend infrastructure using event-driven microservices, enabling real-time device communication, automation rules, and analytics. The system processes billions of telemetry events monthly with ultra-low latency requirements. I designed the edge-to-cloud communication protocol, implemented sophisticated device provisioning workflows, and created a robust testing framework that reduced deployment cycles by 60%. The platform supports multiple device protocols including Zigbee, Z-Wave, and MQTT, providing users with a unified experience across diverse smart home ecosystems.
Key Achievements
- Architected platform handling 5 million+ connected devices across 120+ countries
- Reduced message processing latency from 500ms to 50ms through optimization
- Implemented comprehensive testing framework reducing production bugs by 75%
- Designed multi-protocol device gateway supporting 15+ IoT protocols
- Achieved 99.95% uptime across global deployment spanning 8 Azure regions
