    Executive Summary

    Engineered a high-density, real-time observability dashboard designed for monitoring distributed system health and performance. This interface provides a centralized view of critical operational metrics, including System Uptime, Service Response Times, and Resource Availability, allowing SRE teams to identify bottlenecks and mitigate outages before they impact the end-user.

    Technical Deep Dive & Architectural Impact

    Real-Time Performance Monitoring: Developed a front-end architecture capable of visualizing rapid-fire telemetry data, focusing on “at-a-glance” status indicators for high-volume online resources.

    Latency & Throughput Visualization: Implemented intuitive UI components to track response time trends and uptime percentages, enabling technical stakeholders to correlate performance dips with specific system events.

    Information Density & Hierarchy: Designed the layout using modern CSS Grid and Flexbox to present a massive amount of technical data without overwhelming the user, ensuring critical alerts take visual precedence.

    Modernizing Ops Tooling: Framed as a scalable alternative to fragmented CLI-based monitoring or legacy log-viewers, moving system administration into a modern, responsive web environment.

    Key Technologies

    • Frontend: JavaScript (ES6+), Modern CSS (Variables/Grid), HTML5
    • Domain Focus: Site Reliability Engineering (SRE), Observability, Performance Tuning
    • Key Metrics: Service Latency, Uptime Percentages, System Throughput, Error Rates
