Engineered a high-performance API integration that transformed a 33-hour product import into a sub-3-hour process, enabling real-time inventory management for a major German e-commerce operation.
A German e-commerce client with over 530,000 SKUs was trapped in an operational nightmare. Their product import process took 33 hours to complete, creating a cascading series of problems that threatened their business growth.
The client needed a solution that could handle their massive product catalog while enabling near-real-time synchronization with their ERP system via the Rubin API. The existing approach was fundamentally flawed and couldn't scale.
I architected a complete overhaul of their import system, focusing on three core optimization pillars: intelligent batch processing, strategic database design, and asynchronous execution.
Implemented dynamic batch sizing that adjusts based on payload complexity and server load, processing products in optimal chunks rather than one-by-one or all-at-once approaches.
Created targeted composite indexes on frequently queried fields, reducing lookup times from seconds to milliseconds for product matching and update operations.
Built a message queue architecture using Symfony Messenger to handle imports asynchronously, preventing timeouts and enabling parallel processing across multiple workers.
Implemented intelligent caching for category mappings, attribute lookups, and frequently accessed product data, dramatically reducing database queries during imports.
Product synchronization time plummeted from 33 hours down to just 2.8 hours, transforming weekly catalog updates into multiple daily refreshes.
Support tickets related to pricing errors and stock availability decreased by over 60%, significantly improving customer trust and retention.
Optimized delta synchronization reduced unnecessary API calls by 85%, cutting server infrastructure costs by approximately 40% while improving system stability.
Business can now respond to market changes and promotional opportunities in hours, not weeks.
