What was the project at your last job? What functionality did you perform?

At my last job, I participated in the development of a high-load microservice application for processing financial transactions. My main responsibility was designing and implementing backend services in Go that ensure reliable and fast data processing.

The functionalities I performed included:

• Developing REST APIs for interaction with client applications.
• Optimizing service performance, including profiling and bottleneck removal.
• Implementing authentication and authorization mechanisms.
• Writing unit and integration tests.
• Implementing logging and monitoring for quick error detection and resolution.

An example of a simple HTTP service 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 demonstrates a basic HTTP server that I could use as a foundation for more complex services.
