SpeedCheck

International Internet Speed Test

Project #1

Purpose

A web-based speed test that measures real-world internet performance across international connections, providing more accurate metrics than local ISP tests for global services.

Tech Stack

Node.js Express Vanilla JS PWA Prometheus Jest

Key Outcomes

1

Built a production-ready backend with full observability stack (Pino logging, Prometheus metrics, circuit breaker pattern)

2

Implemented PWA with automated cache-busting for offline functionality

3

Discovered that international speed testing reveals more realistic performance metrics for global cloud services

4

Created educational content explaining the difference between local vs. global speed measurements
