The IT industry is attractive from any angle, both for career professionals and entrepreneurs alike. It is one of the most rapidly developing sectors of the economy, which should come as no surprise, given that IT is a fairly young and promising field, yielding innovations which greatly simplify our lives.

From a beginner wanting to master the field, to an experienced developer keeping their finger on the pulse, anyone interested in IT wants to know the trends and professions that will be in demand the following year. But even within such a multifaceted industry, there are those professions which are losing their relevance, as well as those that seem to explode out of nowhere. That’s why we have studied the data, read the analyses, and now we are going to share with you the trends that are most likely to be popular in the near future.

Developers are always at the Top

First, we would like to turn your attention to the annual Stack Overflow reports. Reporting over the past two years indicates that the full-stack and back-end trends are leading in IT. Front-end developers take third place, followed by enterprise programming (creating software solutions for business), and rounding out the list is mobile application development.\n There haven't been any drastic jumps in Stack Overflow statistics over the past few years, so it’s safe to assume that the trend will continue in 2021.

Not just programmers are needed

Of course, IT needs more than just developers. The whole system is built on a foundation of teamwork. So, in 2021, testers, business analysts, UX/UI designers, project managers and HR specialists will be in demand. Based on our observations and the demand for specialists in the labor market, we would like to present you with a list of the 5 most in-demand professions of 2021.

1. Data Scientist

There are virtually no limits on salaries for big data experts, and the profession is so in demand that many people call it the most promising trend in IT.

The scope of tasks that a data scientist undertakes can be quite extensive, depending on the industry in which they work. The most popular tasks include the following:

  • Solving business problems using a large amount of unsystematic data
  • Working with various programming languages, including SAS, R and Python
  • Collecting large amounts of data and converting them into a more convenient format

2. Web Developer

Web development has been one of the most in-demand professions in the IT field for more than 15 years. It has a fairly low entry threshold; it’s enough to know HTML/CSS at an intermediate level to create simple, but functional landing pages. So, there are a lot of newcomers here.

A huge plus of the profession is that it is perfect for remote work and freelancers.

3. Mobile App Developer

Smartphone shopping has long been a common practice for most people around the world. This is one of the reasons why the field of mobile application development is more relevant now than ever.

A list of the main responsibilities for developers looks like this:

  • Mobile application layout
  • Frontend and backend programming
  • User interface design

Developers of mobile applications are almost always multitasking, so a results-oriented mindset and a high stress tolerance are important personal characteristics for a specialist in this area. Since the field is very dynamic, curiosity and the desire for constant growth and development as a professional are important.

4. Web designer (UI / UX)

Web designers have always been popular, but in the last 5 years the number of specialists who work not only with images, but also with user experience has grown significantly. A UX designer is faced with the task of not only designing a beautiful website, but also making it simple and intuitive for every user.

Specialists use various testing systems and analytical programs in their work. Typical tasks for a web designer include:

  • Prototyping a future site
  • Developing layouts for landing pages, online stores, service sites and online services
  • Finalizing the design according to customer preferences and factors related to user behavior

This profession is uniquely suitable for people with creative minds who possess the necessary graphic tools to bring creative ideas to life. A highly sought-after web designer will also have the skills to design an interface and work with analytics systems.

5. DevOps Engineer

DevOps is one of the fastest growing divisions of the IT industry. This is a strategically important specialty for the development of any software.

DevOps specialists are primarily interested in large IT companies that release large quantities of products and need to automate the development, testing and release processes of projects. And with the advent of artificial intelligence algorithms and big data analysis, DevOps has many opportunities to further strengthen and automate product development and improvement processes.

Let's take a look at the popularity of languages and technologies used in the industry. Today JavaScript is one of the most widely used programming languages around the world and works almost everywhere: browsers, servers, mobile devices, cloud solutions, containers, microcontrollers, etc.

First of all, the growth of TypeScript is certainly worth noting: it looks like it is set to become the main language of the JavaScript ecosystem. This year it surpassed C++ in popularity for the first time. And for the first time in several years, we saw a decline in the share of Python. Perhaps the use of Data Science has reached a saturation point.

So, let's examine the top five most popular technologies:

JavaScript

Over the years, JavaScript has evolved into a high-level and dynamic programming language. The language's first significant breakthrough came in 2009 when Ryan Dahl released the cross-platform runtime environment Node.js and allowed JavaScript to be run on the server side.

In 2021, JavaScript is full of frameworks for different life situations, and the language is already being used for developing mobile applications. But the most popular trend, of course, is web development and for these situations the language supplies popular frameworks such as React JS, Angular, Vue JS, etc.

Today JavaScript is one of the most widely used programming languages around the world and works almost everywhere: browsers, servers, mobile devices, cloud solutions, containers, microcontrollers, etc.

Java

Good old fashioned Java is one of the most popular programming languages for developing server applications and mobile applications for Android.

Developers use Java mainly to create mobile and web applications, games, database-driven software, cloud solutions, and more.

Java is an object-oriented programming language that does not require any special hardware infrastructure, is easy to manage and has a good level of security.

What's more, Java is easier to learn compared to languages like C and C ++. Unsurprisingly, nearly 90 percent of Fortune 500 companies rely on Java for their desktop applications and in-house development projects.

C#

In 2000, the technology giant Microsoft decided to create its own object-oriented C-like programming language C #. Today, C # is a multi-paradigm programming language widely used on the Windows platform, the iOS/Android platform (thanks to Xamarin), and the Linux platform. C # is the best programming language for a wide variety of tasks. This language is mainly used for Windows development, but recently, thanks to the Unity game engine, it has become widely applied in the development of cross-platform games. C# is used to create web applications and is also widely used in web application development.

Python

Python is the most popular language among developers of machine learning, data analysis and web application development. As we can see, the growth of the language’s popularity continues to trend upward, so there is no doubt that Python is more popular today than ever and many developers should consider it.In many cases, Python serves as a first programming language for beginners. There are obvious reasons for this, for example, the language has a friendly syntax, is easy to install, has a huge number of libraries and frameworks, and is very often used in technology startups.

As far as libraries are concerned, there is a module available in Python for almost any occasion. It also has many powerful machine learning and data analysis libraries such as Keras, Tensorflow, scikit-learn, NumPy, etc.The language is also widely used in the development of web applications. With the advent of popular libraries such as Django and Flask, the process of creating websites and APIs has become easier than ever. YouTube itself and the Google search engine use Python in their algorithms.

PHP

Many people were most likely not expecting to see this language on this list. Despite the fact that the PHP language is already quite old, has many flaws in the architecture and lags far behind its competitors, it is still widely used in many post-Soviet companies. Like Python, PHPis yet another programming language created by a single developer as a side project in the 90s.

Later on, more functionality was added to the PHP product, and it organically evolved into a full-fledged programming language. PHP is currently a general-purpose dynamic programming language that is mainly used for developing server-side web applications. PHP is losing its appeal and popularity with the rise of client-based web application development through JavaScript. PHP is an open source language used for writing command line scripts and server side scripts. The language is also widely used to create e-commerce applications, dynamic web applications, content-heavy applications, and more. The language is very flexible and can be embedded in HTML or HTML5 formats.

Hot trends

We must note that this is not the most accurate criterion for determining the demand for programming languages. It is calculated based on the frequency with which the name of the language occurs in search queries of the most authoritative sites like Google, Wikipedia, Amazon, etc.

When deciding which programming language to learn, it is important not to get carried away by hot trends and popularity competitions. The best programming languages to learn in 2021 are likely to be the same languages learned in 2017 and 2018, and will continue to be the same over the next few years. Although the field of computer programming is changing rapidly, the languages discussed above have proven to have staying power. By learning one or more of these languages, you will be in a great position not only this year, but also in the years to come. As you begin your journey into the world of programming, only you can decide which programming language to learn. Base your choice on your own interests and the type of software development you want to be involved in
