Can you tell about examples of services you have implemented in your experience?

In my Go experience, I have implemented several services, for example:

• REST API for user management using the Gin framework. The service provided registration, authentication, and CRUD operations.
• Microservice for message queue processing with RabbitMQ, which asynchronously handled tasks and updated the database state.
• Monitoring service that collected metrics and sent them to the Prometheus system.

Example of a simple HTTP service in Go with Gin:

package main

import (
    "github.com/gin-gonic/gin"
    "net/http"
)

func main() {
    r := gin.Default()
    r.GET("/ping", func(c *gin.Context) {
        c.JSON(http.StatusOK, gin.H{"message": "pong"})
    })
    r.Run() // starts the server on :8080
}
