What approach to designing software solutions do you use in your work?

In my work, I adhere to a software design approach based on the principles of clean architecture and SOLID, which helps create maintainable and extensible code.

Key points:

• Separation of concerns: each component is responsible for its own task.
• Use of interfaces and abstractions to reduce coupling.
• Minimalism: avoiding premature optimization and unnecessary complexity.
• Focus on testability: designing code so that it can be easily covered by unit tests.

In Go, this is often expressed through the use of small interfaces and composition instead of inheritance. For example:

// Interface for data storage
 type Storage interface {
     Save(data string) error
 }

// Implementation of the interface
 type FileStorage struct {}

 func (fs *FileStorage) Save(data string) error {
     // logic to save to a file
     return nil
 }

// Usage
 func Process(s Storage) {
     s.Save("data")
 }
