Experience
Data Aggregator for Product Management Systems
I was the lead engineer responsible for delivering a system that manages and aggregates data from multiple product management platforms (such as Shopify, WooCommerce, and so on) and exports the inventory results to advertising platforms (Facebook, Google)—enabling online advertising.
The main constraints of the system are:
• Synchronization duration
• Efficient data storage strategy for dynamic and vast amounts of data
• User-friendly configuration of the system that abstracts away the challenges of 2-way-sync with multiple platforms (similar to Git merge conflicts)
• API rate limits for various platforms that we integrate with
