A performance-driven advertising product that enables brands and sellers to promote products across Hepsiburada with advanced targeting and optimized ad placements.
Overview
Sponsored Products was developed from the ground up for Hepsiburada's advertising ecosystem. It enables brands and sellers to promote products prominently with advanced targeting, optimized ad placements, and scalable campaign delivery. The backend work combined .NET Core and Golang microservices with Kafka-powered real-time data processing, Redis caching, MongoDB storage, Elasticsearch/OpenSearch search infrastructure, and Google BigQuery analytics workflows. The project improved merchant advertising capabilities, supported revenue growth, and included search-quality work such as solving product rotation issues in Sponsored Products.
