Experience
Sponsored Product Aggregation Platform
The platform integrates with two distinct external vendors. It fetches product ads from both sources, normalizes their data structures, merges the results, and exposes a single, consistent API response to downstream applications.
The navigation data are stored in a GCP BigQuery table, which supports a reporting application for informed decision-making.
Key features include real-time vendor API consumption, reactive non-blocking data processing, automatic result merging, structured logging for observability, and secure access through OIDC/OAuth2. The system is built to support high throughput while maintaining low latency, making it ideal for modern adtech and recommendation systems.
