The Problem

Enterprise hotel properties needed a backend that could detect fire and hazard events in real time and alert personnel immediately — reliability wasn't optional. The core problem was ensuring system integrity for automatic, instant incident alerts.

02

Strategy & Solution

  • Designed functional and configuration specs for a scalable hazard-monitoring backend.
  • Built the IoT pipeline on AWS Lambda and AWS IoT Greengrass.
  • Ran end-to-end testing to guarantee system integrity before deployment.
03

Impact

  • Hit 100% API test coverage across the system.
  • Cut real-time hazard-incident retrieval latency by 15%.
  • Delivered a production-ready safety architecture for enterprise deployment.
