Implementing a High-Performance Carousel with SAP Commerce Cloud

Implemented a real-time product carousel for Red Bull Shop, powered by SAP Commerce Cloud (C/4Hana).

The carousel dynamically showcased products using an influence matrix, driving user-centric recommendations across 100+ countries.

How I solved it:

Designed a real-time ranking engine with Apache Flink, Java 8/11, Elasticsearch & ReactJS.

Processed clickstream data in 24-hour & 7-day sliding windows, updated every 5 minutes.

Calculated conversion & revenue metrics, applied score normalization + coefficients for smarter rankings.

Delivered real-time updates through Elasticsearch for seamless customer experience.

Impact: The adaptive ranking engine boosted conversions & sales by promoting the right products at the right time, significantly improving carousel performance and overall customer engagement.
