Case Study
Chrome extension for automated, real-time monitoring of event streams
A comprehensive automated QA system for live streaming events featuring Chrome extension monitoring, Node.js scheduler, and Microsoft Teams integration. Provides real-time alerts, retry logic, and headless health checks for reliable streaming operations.
Live streaming events require constant monitoring to ensure quality and uptime. Manual monitoring is resource-intensive, prone to human error, and does not scale for multiple concurrent streams. Organizations need automated solutions that can detect issues in real-time, provide immediate alerts, and integrate with existing communication platforms like Microsoft Teams for rapid response.
I developed a comprehensive automated QA system consisting of a Chrome extension for browser-based monitoring and a Node.js scheduler for server-side health checks. The system monitors live streams in real-time, implements retry logic for transient failures, and posts automated alerts to Microsoft Teams channels. It includes headless health checks and provides JSON status feeds for downstream dashboards.

Streams Supported
Concurrent monitoring capacity
The system employs a hybrid architecture with a Chrome extension handling browser-based monitoring and a Node.js backend providing scheduling, health checks, and integration services. The extension monitors DOM elements and network requests, while the backend performs headless browser checks and manages communication with Microsoft Teams API. All components communicate through a centralized status system with comprehensive logging.
Challenge
Detecting streaming issues across different platforms and formats
Solution
Implemented a multi-layered monitoring approach combining DOM element detection, network request analysis, and headless browser checks for broad platform coverage.
Challenge
Ensuring reliable alert delivery without spam or false positives
Solution
Developed intelligent filtering and retry logic that distinguishes between transient issues and real problems, with configurable thresholds and cooldown periods.
Challenge
Integrating with Microsoft Teams for fast team notifications
Solution
Built robust API integration with structured message formatting, retry behavior, and rate limiting to ensure reliable alert delivery.
