Tell me about the most complex or interesting task you have successfully implemented in the last six months.

Over the past six months, one of the most interesting tasks was developing a high-performance HTTP server in Go that handles a large number of concurrent requests with minimal latency. The main challenge was efficient goroutine management and network optimization. Ultimately, stable operation under load was achieved by utilizing Go's built-in concurrency and profiling features.

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 example can be extended to support more complex logic and optimizations.
