A web developer is a specialist who develops websites and online applications.

If speak about major projects, then several specialists are involved. Someone is responsible for the design - appearance, someone - for the technical aspects.

Features of the web developer profession

Previously, it was enough to have skills in working with HTML, CSS and knowledge of the basics of working on the web. Now this is not enough.

And the developer should not only be aware of what html tags are, but also know and understand related tools. How to set up API integration, how to write scripts, in what languages, how to properly layout the layout, and ensure the adaptability of the resource.

What does a web developer need?

The client always needs better and faster. And cheaper.

To speed up the process, developers use various libraries. Programming languages ​​are constantly acquiring new frameworks. The developer constantly needs to keep his finger on the pulse of new technologies. To differentiate yourself from your competitors, it is important to be the first and quickly introduce new tools and technologies into your work.

These include, but are not limited to, GitHub, smart IDEs, build tools, and cloud computing storage.

Web developer salary

Salary is determined by several factors. On average, it ranges from 80,000 rubles to 130,000 rubles, depending on the level of proficiency in programming languages ​​and experience in the field of web development. A developer working directly for a company earns less than a freelance developer. This is due to the fact that part of the money earned goes to the company’s share. However, working for a company provides you with a stable and continuous flow of projects, which is not the case with working as a freelancer. Although average income freelancers vary greatly, some of them claim that you can earn up to 300,000 rubles working as a freelance web developer.

But much more common is a monthly income of 100,000 to 150,000 rubles for new freelancers and from 150,000 to 200,000 rubles for well-established specialists. These figures are based on averages for Russia as a whole.

Of course, not all payments are made in cash. Some developers will give up a certain amount of cash in favor of free advertising, referrals or other services. They will accept agreed quantities of free or discounted products from their customers in addition to the amount paid. Thanks to clients, you can receive copies of paid programs for free.

How to become a web developer

There are many paid and free online courses that can teach you programming. Their advantage is accessibility and structure. However, not all courses may suit your needs. The best way to learn programming is to have a professional on hand who can advise you on all the challenging learning topics.

7 Must-Have Points to Start a Successful Web Career

1. Create your own portfolio website. Your portfolio is the first thing potential employers will look at when considering your candidacy, so it should be a realistic reflection of all your skills.
2. Fill out your portfolio with projects. Now that you have your own website, it's time to fill it with your projects. Include in your portfolio any order that you have made for companies or your individual clients(with their permission). Don't worry if your portfolio is minimal - over time you will accumulate a sufficient number of worthy works.
3. Take on non-budget projects. A great way to fill out your portfolio is to implement simple, frequent free projects. They can be browser games, social networks for a narrow circle of friends, adaptations of various photo editors. This will give you the opportunity to gain experience and improve the credibility of your portfolio.
   Projects do not have to be large-scale. You could, for example, build navigation for a local restaurant's website or create a newsletter for a charity.
4. Participate in developer conferences. This is the most The best way meet people with similar interests who solve exciting problems. You can test your coding skills, learn from others, and possibly win prizes such as gift cards, software, travel and cash.
5. Meet technicians online. Continue to network and learn more about the industry by meeting people online. The easiest way to do this is through Tech Meetup groups.
6. Follow industry news. You don't have to be an expert on every topic. Just stay up to date with the hottest events in the industry. This is easy to do: you can read blogs or tech news sites over breakfast, listen to podcasts, or scroll through Twitter while you walk the dog.
7. Find out more. In addition to learning the news, you should learn new skills and tools. This will make you much more in demand.

The short answer is that they create and maintain websites.

But what exactly this looks like depends largely on the type of work the developer is doing. The good news is that web developers are highly in demand and although they work very hard, they can expect comfortable pay and a healthy work-life balance. This is a profession that rewards people who solve real problems and enjoy creating.

More detailed explanation from learn.org:

Web Developer Responsibilities

Your job as a web developer is to present your client's products and services to a wide audience by creating attractive and functional websites. You will likely be expected to identify a potential user audience and be able to design a site that appeals to that audience. Your job may involve meeting with clients to discuss their wishes for a website or discussing how to keep their site functioning and up to date. You can design the appearance, creating a visually appealing home page and user-friendly design. You can also write content for the site.

Once the site is up and running, you will need to ensure that it functions in all browsers by periodically testing and updating accordingly. The client may also ask you to include interactive features on their site using the language Visual programming Basic or Java.

Where do you work

Web developers can work for large corporations, small companies, or as freelancers. Most positions will require you to work 40 hours per week, although others - especially freelance positions - will allow you to enjoy a flexible schedule. Sometimes you will have to work weekends or non-business hours to perform site maintenance or emergencies.

another skills

You will need good knowledge technology and understanding how computers and web servers work. You will also need to be familiar with a variety of software languages, web applications and web programming languages, such as hypertext language markup (HTML), Ruby on Rails and C++. Since this is a very client-oriented and project-oriented field, you will be required to communicate effectively, set goals and deadlines. You will also have to have an understanding of design principles.

Let's take a look at the key points:

• Developers often work for clients who want to bring their product or service online.
• The work is usually highly project focused and involves collaborating with a team of people who help match the client's requirements to the final product.
• Not all developers work for external clients... The "client" could be the company you work for, an organization, a government agency that needs a website or web application.
• It's quite fun, you actually create things that people use, and you get to play with lots of new toys. How can you not love it?

Important Differences

"Frontend" vs. "Backend" developers

Frontend:

"Front-end" usually means those things that you directly see on the site in the browser. This shows how the content is presented, including all the small elements user interface like menus, drop-down menus, beautiful animations and modals.

Front-end developers often focus on understanding HTML, CSS, and Javascript as these languages ​​run in the browser. They don't necessarily focus on making things "pretty" (which is often left to designers), but rather on making sure information is presented effectively and the user experience on the web page is as seamless as possible. Today we run more and more code directly in the browser.

Backend:

"Backend" generally refers to the part of the application that lives on the server. The backend is more focused on ensuring that all the necessary data is correctly sent to the browser. This part of the iceberg is below the surface... a lot of things have to work correctly to get the data to the front end where it can be displayed correctly.

Google may be a pretty simple search engine from our perspective, but they employ an army of engineers to make sure the gears you can't see work properly.

Full stack:

"Fullstack" developers work simultaneously with both sides. Although each of the “ends” includes the study large quantity information, fullstack developers can comfortably “communicate” simultaneously with the database and the browser. It's quite popular these days to look for developers with a lot of experience working with both sides of a web application (and that's exactly what we teach here).

Web Developer vs Web Designer

So if we have backend developers and frontend developers, then who makes the website really beautiful? Who puts together the images, logos and color schemes? This is the job of a web designer. While they have historically been less involved in the actual programming of pages, nowadays even designers are expected to be able to roll up their sleeves and write a little code when the time comes. Some of the best web developers come from the design field.

Websites vs. Web Apps

Not everyone can agree on what differentiates the two, but generally websites are more designed to display static (unchangeable) content, while web applications require "smart" code running on the server (the kind you'll learn to write) to create dynamic content.

More specific example: Think of coming to a regular website as opening a document (say e-book) on your hard drive. Your computer will find it, open it, and show it to you.

Coming to a site controlled by a web application is similar to the previous example, but the e-book is no longer sitting there waiting for you to open it. Your eBook request is caught by a sneaky little app that checks what you're requesting and then dynamically generates it for you the right book, completely customized for you (okay, it could be as simple as extra line, which says "This book was opened" and is followed by today's date).

This is a more or less noticeable difference between a server that simply shows you static HTML and a server that dynamically generates for you desired page using some Ruby on Rails code.

The Internet has almost 3.5 billion users and over a billion websites. The rapid development of information technology has led to the emergence of professions that no one even thought about 10 years ago. The top line in the rankings of the most in-demand and highly paid IT specialties is occupied by the profession.

There are more than 11 million web developers of various profiles and levels in the world. However, according to CMS data Magazine and “Runet Rating”, 62% of companies and web studios are experiencing an acute shortage of personnel. Here's how they answered the question about the web development workforce shortage.

Today, only a quarter of all web studios are satisfied with the number of their full-time employees. It turns out that there are a lot of programmers, but still not enough. Why?

There are several reasons:

• 15.9% of employers believe that the level of education of potential employees does not meet market requirements (no decent portfolio, no experience in teamwork).
• 15% of companies believe that there are, in principle, few qualified web programmers on the market capable of developing complex projects (especially in the regions).
• 7.3% of companies note that many web development specialists prefer freelancing to in-house work.
• 6.3% of web studios believe that cooperation does not work out due to a mismatch between the salary expectations of applicants and the capabilities of employers.

Thus, there are really few developers who are cool, that is, who know the entire cycle of creating a web project and are able to immediately show themselves in action. Those that exist have already been dismantled by large web studios, or they have gone into freelancing, because they understand that on a piece-rate basis they earn more than the salary in some small company.

Take a look, for example, at this graph of the “Runet Rating”.

From the article “The web development market remains a market of “manual” labor”

Freelance developers occupy a fairly large niche in expensive projects. They get 6% of projects worth from 100 to 300 thousand rubles and 8.3% of projects more expensive than 300 thousand rubles.

Web developer required

It’s easy to see that the web programmer profession is in demand. Just go to any online employment service.

There are almost one and a half thousand vacancies in Moscow alone. Among IT companies and web studios for good developers There is a serious fight going on.

28.4% of companies are looking for employees using job resources, 21.4% - through social networks and through recommendations, 16.2% recognize the vacancy section on their own website as quite effective, and 12.7% have been hunting for employees “since schooldays.” , that is, they invite talented students to internships, track medalists and Olympiad winners, organize competitions for students, and so on.

The last path is the most thorny. According to experts, academic education is inert and does not keep pace with new dynamic industries.

The level of preparation of the majority after university is very low. What's scary isn't even the fact that people with programming backgrounds don't really know how to program. The weakness of systems thinking is frightening.

Vladimir Zavertailov, founder and head of the Sibiriks Internet studio

Therefore, to become that cool web developer that companies will fight for, you don’t need a diploma - you need knowledge.

Qualification

An employer usually understands a web developer as a universal full-stack specialist.

Full-stack consists of front-end and back-end development. Front-end developers ensure the creation appearance website (portal, project). Back-end development includes the shadow side of the resource, what is not visible to the user, the inside of the site. But, regardless of specialization, a web programmer must know the full cycle. Without this, it is impossible to imagine how the piece of the task that you are implementing will integrate with the overall project.

Today, the standard of web development (full-stack) is the following body of knowledge.

Layout + browser programming language + server language + language for working with databases + framework(s).

You can get such a complex of knowledge at. This is an educational platform where lectures and webinars are collected for those who want to learn programming. The web developer specialization lasts 11 months (plus internship) and consists of several courses.

1. HTML/CSS. These are the basics of website creation. Learning comes through practice: students develop an online store website, while simultaneously studying the properties and capabilities of HTML / CSS.
2. JavaScript- first and second levels. This programming language is designed to make the site alive: it interacts with the resource visitor, responds to cursor movements, mouse clicks and keystrokes. In the first course on JavaScript, the basics are taught; in the second, the acquired knowledge is consolidated.
3. Database Basics. These are 20 intensive video lessons about data storage and processing systems that are accessed using SQL language(Structured Query Language).
4. PHP- first and second levels. This programming language is one of the three most popular. At the first level, students study the principles of object-oriented programming and learn to correctly use the basic constructs of the language. The second level allows you to hone your PHP skills to the point of virtuosity.
5. HTML5 and CSS3. This bundle makes it possible to layout layouts, create and edit static sites. During the course, students go through all the stages of creating an advertising website for a commercial organization.
6. AngularJS/D3.js. Here students learn to work with D3.js in symbiosis with the most powerful framework for building single-page web applications, Angular.js.
7. Yii framework. This is one of the most popular and sought-after PHP frameworks. The lectures cover basic and advanced application templates and develop an analogue of the Evernote program. As homework, students are asked to create a calendar program that can later be used in a portfolio.

You can create a full-fledged portfolio case during a two-month internship from GeekBrains. Here, graduates go all the way from idea generation to project implementation and learn to interact with the team. There is also always a chance to get a paid internship followed by employment in one of GeekBrains partner companies or find like-minded people for a startup.

Cream

And in the end about the most pleasant thing - about money. After all, as mentioned at the beginning, the profession of a universal web developer is not only in demand, but also highly paid.

According to the Tagline agency, web programmers receive 1.8 times more salary than the average resident of Russia.

The average salary of a web developer in the country is 60,310 rubles, in Moscow - 75,270 rubles, in the regions - 46,790 rubles.

This profession has no career ceiling; with its help you can ensure a comfortable old age. By working hard and successfully implementing large projects, you can become the head of the information technology department or even the IT director. Also, web developers quite often choose freelancing and do not depend on anyone. This specialty is also an excellent platform for starting your own business on the Internet.

We all know that the 21st century is the century modern technologies. With the advent of the Internet in our lives, the amount of information we receive and transmit has increased tenfold. This increase was followed by a significant increase in the number of professions relevant in modern world. It turned out that it is not so easy to understand the number of web specialties that have arisen. In this article we will look at one of the most important professions in the IT field - the profession of a web developer.

What are the main responsibilities?

Responsibilities of the developer web applications includes a fairly wide range of responsibilities. In addition to the process of developing websites or applications, the employee will also have to communicate with clients, understand and implement their desires. After the specialist has clarified all the client’s wishes, he begins preparing terms of reference. The more carefully the technical specifications are drawn up, the richer the resource brought to life will be. Next comes the actual process of website development. At this stage, the web developer must apply his skills in programming languages. It is also worth mentioning that a web developer often creates a website design independently, although you can resort to help web designers. So, the site is ready for use, now the specialist must present it to his client, for this he needs to demonstrate to the customer that the finished product fully meets his initial requirements. And, in conclusion, we can say that the developer’s responsibilities also include maintaining the relevance of the site through constant modifications.

So, in order to become a representative of this profession, you need to have a number of essential skills:

• ability to communicate with people, you need to convince the client that your product is ideal for completing their tasks
• possession different languages programming, the desire to constantly improve your skills. Good specialist Must be proficient in at least three of the most current programming languages.
• mastery of skills web design. These skills will significantly raise your ranking compared to other specialists
  -the desire to constantly be in trend. You must follow updates and innovations in the IT field.
  -Ability to process a lot of information at once. A sought-after web developer usually works on several projects at once

Where do representatives of this profession work?

Usually web programs ists are not constrained by the choice between office work and freelancing. You can choose the type of employment that suits you best. If you want a full social package and a clear work schedule, you can get a job in a large company, but if you are closer independent search clients and a free schedule - then freelancing, which is now popular, is ideal for you.

The question immediately arises: what is the difference between a programmer and a developer? The answer is quite simple. A developer is a person whose responsibilities, as we have already found out, include a very wide range of different responsibilities. A developer often has to create something new from scratch. That is, not just write code, but create the architecture of the future site, its design and concept. A web programmer is a person whose task consists mainly of writing various codes. This profession requires a less creative approach; it rather requires high degree professionalism and qualifications. A programmer, as a rule, is responsible not for the project as a whole, but for a small part of it, for which he must write the code.

How to become a web developer

If you decide to try yourself in this field, then you have several options. However, be prepared for the fact that all of them will require a lot of time and patience from you. After all, mastering programming skills in high level not the easiest task.

The first and most obvious option is studying at a university. There you will be able to receive a qualified education and a document, without which you will not be able to get a job in any large company. So if you are aiming to conquer large IT organizations, then get higher education- required condition.

If you don’t have the opportunity to study at a university, then . They will teach you the basics of the profession in a short time, and then you will be able to develop your skills on your own.

If the courses are not suitable for you, then you can take the most difficult path - the path of self-education. However, please note that this option is only suitable for those who plan to engage in web development exclusively for themselves.

So, we found out who a web program developer is and what he does. And if you suddenly decide to take up this popular and profitable business, then good luck to you in realizing your plans!
