BrickMonitor

Overview

A public showcase demo demonstrating Jezweb’s product data pipeline capabilities using LEGO sets. While a private e-commerce client project (pool supplies) is impressive but password-protected, BrickMonitor provides a shareable proof-of-capability that potential customers can explore firsthand.

The Problem

Jezweb’s e-commerce data pipelines are impressive when you see them, but:

• Client projects are password-protected and confidential
• Niche product categories (pool supplies) have limited appeal
• Potential customers can’t experience the technology firsthand

Solution: Create a public, shareable demo using a universally appealing product category that demonstrates the same capabilities.

Why LEGO? Universal set numbers (75331 is 75331 everywhere), rich free APIs (Brickset, Rebrickable), universal appeal, strong visual impact, and active secondary market.
