In Go, despite the absence of a traditional object-oriented model with inheritance, it is possible to apply the main principles of OOP — encapsulation, polymorphism, and composition.

For example, encapsulation is achieved using structures and methods:

package main
import "fmt"

type User struct {
    name string
    age  int
}

func (u *User) Greet() {
    fmt.Printf("Hello, my name is %s and I am %d years old\n", u.name, u.age)
}

func main() {
    user := User{name: "Ivan", age: 30}
    user.Greet()
}

Polymorphism is achieved through interfaces:

type Greeter interface {
    Greet()
}

func SayHello(g Greeter) {
    g.Greet()
}

Thus, in my projects, I used structures with methods and interfaces to create a flexible architecture, which facilitated support and extension of the code.
