Tell more about the segmentation logic offloading project: how did you start, what did you finish, what were the results?

The project of segmenting logic outsourcing began with an analysis of the current monolithic system, where segmentation logic was deeply integrated into business logic and complicated support and scaling. The first step was to identify key segmentation functions and define clear APIs for interaction with the rest of the system.

Next, we created a separate service in Go that was responsible only for segmentation. During development, attention was paid to:

• Clear typing and data structures for segments
• Performance optimization, as segmentation is often performed in real-time
• Logging and monitoring for quick problem detection

The project was completed with the integration of the new service with the main application via gRPC, which helped reduce coupling and increase scalability. As a result:

• Support and development of segmentation became simpler
• System response speed increased
• The possibility of independent deployment and updating of segmentation logic appeared

An example of a simplified segmentation service interface in Go:

// Segmenter interface for user segmentation
type Segmenter interface {
    SegmentUser(userID string) ([]string, error)
}

// Service implementation
func (s *segmentService) SegmentUser(userID string) ([]string, error) {
    // segmentation logic
}

This approach allowed for clear responsibility separation and improved code quality.
