Tell us about specific architecture-related tasks you have handled, and your personal contribution.

In the context of architectural tasks, I was involved in designing and optimizing microservices architecture in Go. My contributions included:

• Developing modular and easily extendable components using interfaces and design patterns.
• Implementing a messaging system between services via gRPC and REST API to ensure high performance and scalability.
• Optimizing database interactions, including connection pooling and caching.
• Setting up monitoring and tracing (e.g., with Prometheus and OpenTelemetry) for quick identification of bottlenecks.

Example code using an interface for storage abstraction:

// Storage interface for data operations
type Storage interface {
    Save(data Data) error
    Load(id string) (Data, error)
}

// Storage implementation for a database
type DBStorage struct {
    // database connection
}

func (db *DBStorage) Save(data Data) error {
    // logic to save to DB
    return nil
}

func (db *DBStorage) Load(id string) (Data, error) {
    // logic to load from DB
    return Data{}, nil
}

This approach allowed easy swapping of implementations and testing components without dependency on specific technologies.
