What did you do at your last job?

At my last job, I was involved in developing high-load services in Go. The main tasks included:

• Designing and implementing microservice architecture for processing large volumes of data.
• Optimizing performance and reducing latency in request processing.
• Developing RESTful APIs and integrating with external systems.
• Writing unit and integration tests to ensure code quality.
• Working with databases (PostgreSQL, Redis), setting up caching.
• Participating in code reviews and mentoring junior developers.
• Automating deployment and monitoring processes.

Example code for 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 experience allowed me to gain a deeper understanding of language features and building scalable systems.
