Tell us about the last project you worked on. What is your current role?.

In my last project, I worked on a monitoring and alerting system for a distributed application in Go. My main task was to develop microservices responsible for collecting and aggregating metrics from various sources. I implemented REST APIs for frontend interaction and integrated with a database for storing time series.

I also focused on optimizing service performance, implemented caching, and wrote unit tests for key components. During the project, I used goroutines and channels for efficient handling of concurrent requests.

Here's an example of a simple HTTP server in Go that I could use for API:

package main

import (
    "fmt"
    "net/http"
)

func metricsHandler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "{\"cpu\": 0.75, \"memory\": 512}")
}

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