Introduction: Why Go is the Choice of Modern Backend

Go (or Golang) is a language created within Google to solve problems of high load and concurrency. Today, it is used to write microservices, cloud platforms (Docker, Kubernetes), CLI utilities, and high-load APIs. The demand for Go developers is steadily growing: according to Habr Career, the number of Golang vacancies has increased by 40% over the past year. However, competition among junior specialists is still high. How to stand out? How to create a resume that gets noticed? And what do you really need to know for an interview? Let's break it down step by step.

Step 1. What a Junior Go Developer Should Know

Employers expect from a candidate not just syntax, but an understanding of the language's philosophy. Here is the minimum set of competencies:

Basics of Syntax: data types, structures, interfaces, goroutines and channels.
Standard Library: net/http, encoding/json, sync, context.
Working with Databases: SQL (PostgreSQL, MySQL) and ORM (e.g., GORM).
Testing: writing unit tests with testing and mocks.
Tools: Git, Docker, basic knowledge of Linux.

An example of a simple HTTP server that you should be able to write in an interview:

package main

import (    "fmt"    "net/http")

func helloHandler(w http.ResponseWriter, r *http.Request) {    fmt.Fprintf(w, "Hello, Go developer!")}

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

Advanced Topics for Growth

If you have already mastered the basics, add to your portfolio:

Graceful server shutdown.
Working with middleware (logging, authorization).
Writing database migrations.
Profiling and benchmarks.

Step 2. How to Create a Go Developer Resume

A resume is your main marketing tool. It should be concise and technically accurate. Use the following template:

1. Header and Contacts

Specify a clear specialization: Go Developer (Junior/Middle). Do not write "programmer" — it's vague.

2. Skills (Hard Skills)

Group them by category:

Language: Go (Golang), knowledge of goroutines, channels, interfaces.
Databases: PostgreSQL, Redis, MongoDB.
Infrastructure: Docker, Docker Compose, CI/CD (GitHub Actions).
Other: REST API, gRPC, RabbitMQ/Kafka.

3. Work Experience and Projects

Even if you have no commercial experience, describe pet projects. Use the format: "Task — Action — Result". Example:

"Developed a REST API for URL shortening in Go. Used PostgreSQL, Redis for caching, Docker for containerization. Load testing showed 5000 RPS without errors."
