How To Hire Golang Developers?

As more firms implement long-term initiatives to improve the speed of their backend systems, Golang developers are becoming increasingly popular. However, Golang programmers are still more difficult to come by than JavaScript or Python programmers.

However, it's safe to conclude that the language's early adopters are enthusiastic and have a good understanding of how to apply it in their field of work.

Golang is a general-purpose programming language that may be used for cloud and network services, web development, DevOps and site reliability, and even command-line interfaces. If you want to create a web application that uses Go on the backend, you'll need to hire a Golang developer that has worked on web apps before.

Backend developers are more likely to learn Golang, making full-stack Golang engineers with extra JavaScript more difficult to come by at this moment. This is likely to change as Golang's popularity grows, as it's one of the few languages that delivers on its promises of improved efficiency and usability.

Why Do You Need To Hire a Golang Developer?

Golang is a lightning-fast programming language. It is said to be faster than Python and comparable to lower-level languages such as C. That's by design, as Go was created by Google developers to be extremely fast. When dealing with concurrency, this speed is extremely useful. Concurrency occurs when numerous programs execute at the same time, often on different cores, and can communicate with one another via a shared memory address.

Concurrency is a difficult concept to grasp, yet Go handles it far better than older single-threaded programming languages.

Given that you have a compelling user experience that can attract and please consumers, speed and delivery are perhaps the two most crucial factors in modern digital applications.

Golang allows developers to easily tap into higher performance in a way that is very distinct from what is possible with other languages. To get the most performance out of older languages, you'll need a lot of technical know-how and language-specific information.

Skills Required For a Golang Developer:

1. Concept of Goroutine

A Goroutine is a function that runs independently of other Goroutines in your program while also interacting with them.

This means that you can work on multiple things in Go at the same time while remaining independent. As a result, if one activity becomes stopped or requires input, the others can proceed without being hampered by faults or delays elsewhere in the application.

Goroutines, according to Stack Overflow's John Biggs and Ben Popper, are "worth the price of admission alone" for the Go language.

Any aspiring Go developer should be very familiar with how to launch and synchronize goroutines to design robust, highly concurrent apps.

2. Patterns and frameworks for Go Channel

Go channels are the communication and data-sharing channels for concurrent Goroutines. This method synchronizes the exchange of any data that flows between two Goroutines.

When concurrent threads need to share data, the data is 'locked' in many other programming languages. This leads to a slew of memory management concerns.

Go solves this problem by transmitting the value of a data variable from one thread to another via Go channels, with both threads 'waiting' for the value to arrive at its destination. This 'waiting' ensures thread synchronization without the hassles associated with locking variables.

The two types of Go channels (buffered and unbuffered) and how to utilize them to construct the most common concurrency patterns and frameworks, such as producer-consumer queues and condition variables, should be extremely known to your target Golang developer.

3. Commenting by Godoc

All programming languages provide facilities for documenting and communicating code. The game of Go is no exception! However, Go comments can do more than just provide basic information.

Godoc, Go's built-in documentation tool, is the most miraculous of these features.

Godoc looks for comments in all of the Go source code and combines them to provide the package's documentation in HTML or plain text.

This makes it simple to generate user documentation that is tightly tied with the relevant code: for example, you can switch between a function's description and its implementation with a single click using godoc's web interface.

Go developers should understand how godoc parses comments (for example, including package-level comments while ignoring lower levels), as well as the formatting rules that godoc utilizes when converting comments to HTML, and be able to generate clean and effective godoc comments.

4. Learn how to use Go libraries and other tools.

You should move on to the add-on libraries and tools that make Go easier to use once you've mastered the basics of the language.

Frameworks, Go libraries, and databases are the most crucial extras to learn. Many of the other abilities can be picked up on the job or as you go along.

In terms of frameworks, the web frameworks Echo, Beego, Gin, Revel, and Chi are advised to begin with, with Echo being the most crucial for Go.

Go Kit, GORM, Gen, and CLI are the most popular libraries in the Go ecosystem. Working with Go will be significantly easier if you use decent libraries and packages. Each will have its distinct qualities, so choose one that corresponds with your objectives.

In terms of databases, familiarity with relational databases such as PostgreSQL or MySQL is essential.

5. Learn to test with Go

Testing is a valuable talent that most employers will seek. Software testing is the process of determining whether the final software product meets the requirements and runs correctly after it has been deployed.

As a Go developer, you'll be creating real-world products, therefore you'll need to test them for usability and reliability. This includes the following:

  • Testing at the unit level

  • Testing for integration

  • Behavior analysis

  • Testing on a one-to-one basis

For new Go developers, unit testing is likely the most critical. In Go's standard library, there is a built-in testing package. However, because Go errs on the side of minimalism, you may need additional testing tools, such as the popular frameworks Ginkgo and GoCheck. Ginkgo can also be used for integration and behavior testing.

6. Begin constructing your portfolio

It's time to start constructing your portfolio once you've mastered these processes. This is how an employer will know you have real-world Golang experience. Furthermore, it has been established that the greatest method to master a language is to use it to create working things, thus the more you make, the more you learn.

Creating a portfolio entails:

  • Completing online classes while on the move

  • Taking part in open source Go projects

  • Creating Go projects from the ground up and integrating Go units into existing ones Using Go to solve traditional algorithm problems

  • Taking courses in related technologies (i.e. SQL)

You can create anything you wish to improve your abilities, including personal to-do lists, demo websites, riddles, games, and coding challenges.

Begin with a certificate-granting online course. You might include this on your resume to demonstrate that you understand the fundamentals. Then, on GitHub, concentrate on open source contributions. This shows that you can create real-world projects and use a popular version control system.
