Hire top talented Golang freelance developers with UltraGenius

Golang (or Go) is a statically typed system-level language used for cloud native development, programming large scale servers and distributed systems, and as a replacement for existing infrastructure. Golang borrows run-time efficiency and static typing from C, readability and scalability from Javascript and Python. Go is able to handle multiple requests on server side with very less memory usage.

Javascript fundamentals + ES6

Javascript is most widely used language for developing both client-side and server-side applications and helps freelance Golang developers integrate back-end with the front-end easily. The Golang freelance developer must be clear with the fundamental concepts of Javascript language. ECMAScript 6 (or ES6) is the current version of ECMAScript and is widely used by developers up to a large extent. The freelance Golang developers must be familiar with these ES6 skills –  

  • Arrow functions
  • Blocked scope constructors let and const
  • Advanced object literals
  • Template literals
  • Multi-line strings
  • Modules
  • Module loaders
  • Binary and octal literals
  • Reflect API
  • Proxies
  • Classes
  • Destructuring assignment

Familiarity with Shell scripting

A shell script is designed to sequence and schedule system tasks and provide decision making linkage around them. Shell scripting is designed for performing multiple system level tasks such as creating, managing, and implementing system booting scripts, automating the installation process of a new version of a software, automating the repetitive tasks, and scheduling and executing the system processes. It includes many advantages for a freelance Go developer like interactive debugging, quick start, and fast program or file selection.

Knowledge of Go libraries

The Go language provides a vast set of standard library that includes core packages that can be added to the Golang program saving the developer from writing multiple lines of code which streamlines the development. Some of the popular Golang libraries include – GORM, Gen, Goose, Go CLI, Go Kit, Glide, Authboss, Vegeta, Docker, Ginkgo, Docker, Kubernetes, Fuzzy, Etcd, NSQ, and mgo (mongodb driver). Golang also avails go-echarts library for the developers to work on graphs. GORM is one of the most popular database libraries used in Go and is a featured tool for object relational mapping.

Experienced working with Version Control System (VCS) like Git

To be a freelance Golang developer, you need to have knowledge of version control systems like Git, SVN, TFS and Mercurial. There is mostly use of Git for their work. This helps the team in collaborating and organizing your code; it also makes it easier to maintain the frequent changes that happen in codes. It’s helpful while reviewing old codes with newer ones or pulling from repositories when required or managing commit history as well as adding-committing-pulling (or pull). Along with this, Golang freelance developers must know how to use add, push, pull, commit commands – branching and merging which allows developers to work independently on the code.

Knowledge of Go frameworks and tools

Golang allures software development process by its core frameworks like Revel,  Martini, Gin Gonic, Beego (similar to Django framework in Python), Net / HTTP, Mango, Gorilla, Buffalo, Goji, and Gocraft. The freelance Go developers must have knowledge of Go’s dependency management tools like Godep and Sltr, code generation tools such as Stringer, and router packages like Gorilla Mux. Besides this, the freelance Go developers should know about GoConvey, Ginkgo, Vegeta, and HTTP testing tool. 

Experience in API integration with REST and SOAP APIs

The NET/HTTP library in Go is best for building REST APIs. REST stands for Representational State Transfer defines a set of constraints of how an Internet scale distributed hypermedia system should be. A perfectly designed REST API is similar to a website running in the web browser with an in-built HTTP functionality. It uses GET, PUT, POST, PATCH, and DELTE method to performs operations on data. SOAP stands for Simple Object Access Protocol and uses only HTTP and XML. SOAP has the ability to work with application layer protocols such as HTTP, TCP, UDP, and SMTP.

Knowledge of Goroutines and channel patterns

A goroutine is a function or a method that runs concurrently with other functions in the same address space. Goroutines are similar to lightweight threads and the cost of creating goroutines is much less as compared to a thread. Goroutines internally act as coroutines and are multiplexed among several operating system threads.

Familiarity with Cloud

Golang is widely used for developing secure and efficient software on cloud platforms. Because of its concurrency feature, Golang is also known as ” Language of Cloud”. Golang helps to build large scalable systems maintaining concurrency via Goroutines. The freelance Golang developers must know about application development and deployment using any of the cloud platforms including  – AWS, Azure, or Google Cloud.

Expertise in implementing Microservices

Golang is a good choice for developing microservice and enables freelance Golang developers create applications with high-load services. Go kit library is used for microservices development. It solves the problems that occur in distributed applications and systems so that developers can concentrate on the business logic of programming.

Knowledge of DevOps practices

DevOps is a set of processes that enables faster application development and provides general practices for building the best quality software through the system. Almost all deployment platforms use Golang, so the freelance Go developers should know about Continuous Development, Continuous Testing, Continuous Integration (CI), Continuous Deployment (CD), Continuous delivery, Continuous monitoring, and infrastrucutre as a code.

Understanding of Go's design patterns

The freelance Go developer must have firm understanding of design patterns. A design pattern is a general and repeatable solution to any problem in software designing. Go’s design patterns include – Creational design pattern, Structural design pattern, Behavioral design pattern, Concurrency design pattern, and Stability design pattern.

Experience with deployment tools like Heroku, Docker, and Kubernetes

Docker and Kubernetes helps freelance Go developers manage containers in software development and production. Docker can run in any environment of a developer’s choice like a public cloud service, a remote server, or a laptop,  while Heroku should run in its own cloud environment. Kubernetes is an open source system that provides developers to automate deploys, run and manage containers, scale the deployments, deploy stateful and stateless applications, and many more.

Golang is one of the most demanding programming languages for developing server-side and cloud-native applications. Go is specifically designed for faster application development with least memory usage.  But recruiting the best freelance Golang developers is not an easy task when a large no. of Golang freelance developers are competing to grab the job opportunities.

Top Interview Questions to ask while hiring a freelance Golang developer

A string literal is a string constant formed by a single character or  concatenating a sequence of characters. There are two types of string literals - Raw string literals and Interpreted string literals. 

Raw string literals are the uninterrupted sequence of characters placed between backticks. For example, `UltraGenius`.

Interpreted string literals are the sequence of characters placed within double quotations. For example, "Welcome to UltraGenius".

Slice is a lightweight data structure used for storing homogeneous data with a sequence of variable length. Slice has three components- 

  • Pointer - A pointer points to the first array element which is accessible through slice. The element is not necessarily to be the first element.
  • Length - Length represents the total number of elements present in the slice.
  • Capacity - It represents the capacity up to which the slice can expand.

Goroutines provide the way of executing tasks concurrently with other tasks in the same address space. Goroutines can communicate using the channels which are especially designed to prevent race conditions when the memory is being accessed. The main Goroutine must run in order to run any other Goroutine.

Type Switch is used to check the data type of a variable at run-time. Each Switch contains minimum one case which behaves as a conditional statement and a default case which is executed if none of the mentioned conditions is true.

A Go channel is a way of communication used by Goroutines to exchange data. When freelance Golang developers have multiple Goroutines running concurrently, then Go channels become the most efficient mechanism for communication. Freelance Go developers often use them for notifications and managing concurrency in the program.

The chan keyword is used for creating a channel. A channel can transfer only the same type of data from the same channel, different type of data is not permissible. The channel can also be created using the make() function with a shorthand declaration.

The make() function creates a generic channel, map, or slice values. It returns general type value and not a pointer value. While the new() function works for all types and allocates memory for the variable dynamically at run-time, initializes to zero value, and returns a pointer value to it. 

Golang provides a special feature called anonymous function which has the ability to form closures. A closure is an anonymous function in which the reference variables are declared outside the function. It is similar to accessing the global variables outside the function.

For example, 

package main 

import "fmt"

func main(){

UG:=0

count:=func() int{

UG+=1

return UG

}

fmt.Println(count())

fmt.Println(count())

The output of the program will be - 

1

2

 

One of the unique features of Golang is that it provides automated package testing with custom testing suites. For creating a new testing suite, create a file with _test.go extension that contains a TestXyz function, where Xyz is replaced with the name of the feature which is to be tested. 

After that, place the testing suite file in the same package in which the file needs to be tested is present. The test file does not run during normal execution but  will run only when you execute go test command.
