Are you working?

Yes, I actively work with Go (Golang) and use it for developing high-performance server applications and microservices.

Example of a simple HTTP server in Go:

package main

import (
    "fmt"
    "net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hello, world!")
}

func main() {
    http.HandleFunc("/", handler)
    http.ListenAndServe(":8080", nil)
}

This code runs a web server that responds with "Hello, world!" to all requests.
