Tell us about your experience at Magnit (3.5 years). What tasks did you perform?

At Magnit, I worked for 3.5 years as a Golang developer. My main responsibilities included:

• Developing and maintaining microservices for processing large volumes of data and integrating with internal systems.
• Optimizing service performance, including profiling and bottleneck removal.
• Implementing REST and gRPC APIs for inter-service communication.
• Working with databases (PostgreSQL, Redis), writing efficient queries and migrations.
• Implementing CI/CD processes for automation of build, testing, and deployment.
• Participating in the design of distributed system architecture.

An example of code from the project is a simple HTTP server in Go:

package main

import (
    "fmt"
    "net/http"
)

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

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

I also wrote unit and integration tests, participated in code reviews, and improved development processes.
