Intelligent Data Extraction Platform Engineering for a Dynamic Ecommerce Website
Business Challenge
Dynamic eCommerce pages and SKU-level variations led to data inconsistencies, frequent scraper failures, and high maintenance costs. Scaling extraction across large volumes of product URLs remained difficult.
Tech Stack
Blueprint
Bobcares built an AI-driven, modular extraction platform that handles dynamic content, improves data accuracy, reduces maintenance, and supports scalable data ingestion.
The Challenge
• SKU-level variations caused frequent data inconsistencies across size and color combinations.
• Tight coupling between scraper logic and website DOM structures increased fragility.
• Website layout changes created high maintenance overhead.
• Absence of centralized validation and control reduced data reliability.
• Large volumes of product URLs lacked an efficient processing mechanism.
Why Bobcares
• Engineering modular, API-driven data platforms
• Handling dynamically rendered web content
• Applying AI to reduce structural dependencies
• Transforming internal automation into reusable products
What We Delivered
Key Components and Implementation Highlights
Website-Specific Scraping Engine
A dynamic scraping service was built using Express.js and Puppeteer to handle JavaScript-rendered content. Dedicated APIs extracted detailed specifications, geometry data, and SKU-level variations while managing navigation and state changes accurately.
AI-Driven Universal Scraper
Gemini 2.5 Flash was integrated to interpret raw DOM content without relying on rigid page structures. The AI pipeline identified relevant attributes, filtered noise, and produced standardized JSON outputs, enabling adaptability across brands and websites.
Product Management and Control Layer
An internal management interface allowed teams to preview scraped data, normalize fields, correct inconsistencies, and manage batch URL ingestion. This layer transformed the scraper into a production-grade internal product.
Key Aspects and Modules
• AI-assisted extraction independent of DOM structure.
• SKU-level data accuracy across variants.
• Batch processing for high-volume URLs.
• Centralized data validation and control.
• Modular architecture for easier scaling and maintenance.
