Have you had experience developing or working with the Go programming language?

Yes, I have experience working with Go. Go is a compiled programming language with support for concurrency and a simple syntax, often used for creating server applications and microservices. For example, I wrote a REST API in Go using the standard net/http package:

package main

import (
    "fmt"
    "net/http"
)

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

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

This example demonstrates a basic web server structure in Go.
