Tell us about your current workplace and the enrichment service — what kind of service is it, and what is its responsibility?

The Enrichment service is a component responsible for data enrichment, which means adding additional information to the original data to increase its value and completeness.

For example, in the current project, the enrichment service receives basic user data (such as ID and email) and supplements it with information from external sources: geolocation, demographics, purchase history, etc. This allows other services to work with a more complete and high-quality data set.

Responsibilities of the service:

• Accept requests for data enrichment.
• Integrate with external APIs and databases.
• Process and normalize the received information.
• Cache results to improve performance.
• Ensure high availability and scalability, as the service is actively used in the system.

Such a service helps to centralize the enrichment logic and avoid code duplication in different parts of the system.
