What Does a Web Developer Do? - Web Development Courses

Why you should become a web developer?

This article will introduce you to the world of web development, explain different roles and tools used for developing websites and give you some tips on how to start journey with a web development yourself. We will also discuss if freelancing is a reasonable option and if you can start programming even if you do not have a Computer Science university degree, and where to look for educational materials.

Why you should become a web developer. What you should learn.
  • There are multiple reasons why you should become a web developer yourself. Let’s take a closer look at some of them:
  • Money
    With the incredibly high demand for web developers, companies are willing to do a lot in order to ensure they get the best people from the market. The most obvious way of ensuring this is offering exceptionally huge salaries. It’s also relatively easy to reach high salary level even after 2-3 years of doing software development.
  • Job stability
    High demand for developers allows you not only to maximize your income, but also allows you not to worry about “tomorrow”. If you lose your job for some reason, you can find another one very quickly sometimes without even actively searching for it. Companies often hire “headhunters”. Those are people whose full time job is to actively hunt for the best people on the market. This applies even to freelancing.
  • Freelancing
    Freelance developers are often self-employed and do not have a full time “day job”. They often work with multiple clients and only for a lifespan of specific projects. Why would you choose this way? Freelancing can give you a lot of flexibility due to scheduling freedom. Just like when running a company, you choose your working hours. You want to work only two days in a week? Why not? Additionally, employers are willing to pay even higher salaries when not doing long-term commitments.
  • Remote work possibility
    More and more employers allow their employees to work remotely. If you are self-discipline you can stay home all day long and work from your own bedroom or if you wish, one day you can work from home and another from a beach in Canary Islands. Why not?
  • Challenging tasks
    Developers need to solve problems that utilize a lot of brainpower on a daily basis. If you get bored with repetitive tasks easily, this might be a way for you.
  • Comfortable working conditions
    Developers usually work in air-conditioned offices, sitting on ergonomic chairs in front of a computer with multiple monitors and fast internet access. How much more comfortable than this can it get? Well, some companies allow their employees to sit on bean bags whole days and arrange special play rooms where you can socialize with your colleagues in front of a newest gaming consoles.
  • Working with smart people
    At work, developers get surrounded with other developers, analysts, project managers and so on. This creates a very unique and inspiring self-development environment full of bad technical humor.
  • Multiple career path choices
    You do not need to remain a web developer for the rest of your life. After being a developer, you can become a team leader, project manager, head of IT department or simply just keep advancing in a different technology field. A lot to choose from!
  • Community
    The developer’s community is huge and open to everyone. It can be used as an endless source of technical support or for socializing with like-minded people. When meeting other developers or attending conferences, forget about suits and unnecessary formalities. This is the one huge family.

How does the internet work?

When entering a site address in a browser, users request data from servers. Those can form web pages or web applications. Those terms are not strictly defined, but when you are thinking about web pages you refer mostly to static informational sites (just like the one you are browsing now) and web applications are pages that can perform some advanced logic. A web interface for an email account makes a good example of a web application. Both get implemented by web developers.

What is a web development?

Web development usually refers to activities related to website functionalities development. Web developers ensure that when users interact with a website, it reacts in a certain manner. In order to achieve this, code must be written both on server and client side and communicate well with a database.

Client (Frontend)

Client-side development refers usually to user interface development. In web development’s case it’s the browser that’s running the code displaying a webpage. The big challenge in this case is to make sure that a website behaves in the same way on all browsers.

Server (Backend)

Server-side development is a technique used in Web Development that refers to creating code that it’s being run “on the other side” and which is responsible for dynamic site code generation and database handling.

Database

Databases are special programs designed and optimized for an efficient data storage. They are crucial for any system that needs to persist any kind of data.

Web development vs web design: What is the difference?

These two totally different roles are often misunderstood. Web developers implement website functionalities when designers focus only on aesthetics and usability. Designer’s work results in a non usable aesthetically appealing project while developer’s work results in a functioning rough-looking site.

Web development roles:

When developing web pages, some certain project roles with different responsibilities can be distinguished:

Web Designer

Web Designers are responsible for aesthetics and usability of a web pages and web apps. Their scope of responsibilities do not involve development of actual functionalities. They might use Adobe Photoshop or Adobe Illustrator for creating their designs, when more advanced designers can even build HTML static web pages’ prototypes.

Web Designers are often freelancers that take advantage of scheduling flexibility and remote work. On the other hand, they do not really implement their own ideas, but rather take other people’s ideas and transform them into reality. Their salaries are also smaller in comparison to developers’ because their scope of responsibilities is not that wide. They also get mocked by other developers, because users tend to notice only visual aspects of applications.


Frontend Developer

Frontend Developers are the glue between Web Designers and Backend Developers. They deal with client-side programming and apply designs received from Web Designers.


Their main tools are:

  • HTML: HTML(Hyper Text Markup Language) is a standard markup language used for web pages creation. HTML stands behind almost all web pages in the world. It’s relatively easy, but it’s not enough to create aesthetically-appealing sites. This is where CSS comes into play.
  • CSS: CSS(Cascading Style Sheets) is a style sheet language used for defining styles, layouts and other different features of the visual aspect of your web page. This is the tool that helps you transform a raw HTML webpage into a piece of art.
  • JavaScript: JavaScript is an object-oriented programming language used for defining dynamic actions that occur on your web page or “behind the scenes”, Alongside HTML and CSS, it’s one of the three most important technologies for developing web pages.


Backend Developer

Backend Developers are developers that work “behind the scenes”. They develop server-side logic, manage database connection, design APIs(Application Programming Interface), handle security and authorization.


Their main tools are:

  • Ruby: Ruby is a general-purpose open-source programming language that focuses on simplicity and productivity. It blends object oriented programming with functional approach.
  • Node.js: Node.js is a cross-platform runtime environment for running server-side applications written in JavaScript.
  • PHP: PHP is a very popular and a little bit archaic scripting language that is used for web development that can be easily embedded into html files.
  • Python: Python is a high-level scripting language. Python gained a lot of popularity due to its simple and relatively easy to use syntax.
  • GoLang: Go is an open-source programming language created and maintained by Google. This language got recognition because of its easy syntax and concurrency support provided at language level.
  • Java: Java is a general-purpose object-oriented programming language used almost exclusively for backend-side programming. Java applications are being run on the JVM virtual machine, which allows them to be run on any platform that can run JVM. In the newest Java 8 release, there were functional programming tools introduced.
  • Scala: Scala is a cousin of Java that also runs on JVM virtual machine. Scala gained a lot of recognition due to its extended functional programming support and full interoperability with Java classes.

Backend developers need to deal with databases too. Some of the most popular databases are:

  • MySQL
  • PostgreSQL
  • ElasticSearch
  • Cassandra
  • Redis
  • OracleDB

The biggest advantage of being a web developer is being responsible for core functionalities development. Without backend developers web pages would remain static and unusable. The biggest disadvantage is that backend developers rarely get credited for their job since users often tend to focus on the frontend side which is only a tip on an iceberg.


Full Stack Developer

Full Stack Developer is a one-man army specialist that can both client and server side, and sometimes even a design. Mastery over different layers is in high demand, understanding problems of different project roles makes them a good fit for a potential team leader position. The biggest disadvantage is the necessity of staying up to dates with multiple technology stacks.

What does a web developer do?

As you already know, Web Developers are responsible for building and maintaining web pages/ web apps in general. You might think that web developers spend whole days working on their code, but it’s not necessarily true. While development is the biggest part of a developer’s job, there are other crucial tasks that need to be done. But what activities does this involve? Let’s answer it now:

Analysis

Analysis is a constant part of Web Developer’s job. This involves talking with a client, gathering functional and nonfunctional requirements. This allows to look at a project from bird’s eye view and then plan architecture properly.

Code Review

Before new code gets added to a main codebase, it usually undergoes a Code Review process. This is a small ceremony where other developers go through your code and review it, often suggesting some small fixes. In order to perform a Code Review well, you need to spend some time on understanding other people’s code.

Mentoring

After you reach certain level, you are often expected to share your knowledge with other people and train junior developers.This is often accomplished by Pair Programming, which is an activity where two developers sit in front of one computer and try to solve problems together.

Maintenance

Except for working on new tasks, developers often need to take care about legacy projects. This usually involves solving random bugs and implementing small changes for an already working project.

Meetings

Developers spend a lot of time meeting and talking not only when discussing new features with clients. Developers often organize daily status meetings, where they discuss what did they manage to accomplish on a previous day and what are they going to do on that day. Planning, Retrospectives and Refinement meeting are also very popular. Planning meetings are organized on the beginning of some time period and all developers go through a backlog( a place with all tasks to be implemented) and plan their job for an upcoming period. Retrospectives are special meeting where team discusses what did they manage to accomplish and what could have been done better. Refinements are meetings where developers meet their clients and go through a backlog and make final decisions which task will be implemented.

Do you need a degree to become a web developer?

Studying Computer Science molds you as a general specialist who has an understanding of all technological layers involved. This is a perfect base to build upon and this is something which is extremely difficult to achieve when trying to learn everything on your own.


People, who learn programming on their own, often do not even realize the existence of some issues that are obvious for CS graduates. On the other hand, university degree is not necessary for becoming a developer, but it’s also not enough to be a good one. Most companies do not care about your education, but they do care about you knowing how to do your job properly. Bill Gates and lots of IT startups never got their degree, so being successful without a degree is surely possible

What you should learn to become a good web developer?

Firstly, you need to learn basics of your core tools. As you probably already know, there are 3 common tools for an every Web Developer: HTML, CSS, JavaScript. Besides this you should get to know at least one server-side programming language. Working knowledge of those technologies is a good starting point to build your skills upon. Let’s explore now other qualities that you need to possess in order to become a good web developer:

Frameworks

Knowing syntaxes of programming languages is definitely not enough to start working. In Web Development, there is often no reason to lose time on reinventing a wheel, because in most cases out of the box working solutions are provided by different frameworks. If you browse job offers, you will notice that employers are often more interested in framework knowledge than in a language knowledge itself!

Clean Code

Writing clean code means writing code that is predictable and easy to read and understand by others. Developers often need to read other people’s code. This is why it’s so important to write code in such a way that everyone can understand it as quickly as possible.

IDE Proficiency

Integrated Development Environments are crucial for being productive with writing code. IDEs allow easy code navigation and often support code completion.

VCS Knowledge

Version Control Systems are programs that allow easy code change management. You do not want to store different versions of your code in separate folders or on pendrives. Being proficient with some VCS gives you freedom because at any given time you can easily rewind changes that you made in your code base. The most popular VCS nowadays is Git.

Ability to Use a Terminal

Learning how to use a command prompt is crucial for example for achieving proficiency with Git VCS. You simply can’t access all options from a graphical user interface.

Code Testing

This is one the most important abilities. Having your code test-covered gives you multiple advantages. Firstly, you are not afraid of making changes to your code base, because if you mess up something, your tests will immediately inform you about this. Secondly, if you implement your tests before writing main code(Test Driven Development) , they are a great indication whether you nailed all functionalities properly and that you finally stop coding.

People Skills

As stated earlier, developer’s job consist not only of writing code, but also of interacting with many people. This is why it’s so important to learn how to be communicative and assertive.

Should you be a freelance developer or working for a company?

Both approaches have their advantages and disadvantages. Let’s explore them:

Freelancing

As mentioned earlier, being a freelancer essentially means being an independent contractor that works with multiple clients and usually only on specific tasks and projects without having any long-term commitments. This can be compared to being a one-man company. When freelancing you usually don’t have fixed working hours and you can sculpt your working time according to your specific needs. Additionally, you become your own boss, so you can finally breathe some freedom when noone is micromanaging you. There are also no managers that tell you how to do your job.

Freelancing gives you a lot of freedom and flexibility, but has also disadvantages. For many people the main disadvantage is the lack of stabilization. You have no guarantee that after your job is done, there will be another one. Forget about paid leave or sick days too. You get paid only for the days you actually worked. You need to prepare for a lot of additional legwork too. It’s now your responsibility to reach out and search for a new clients and projects. Some freelancers complain that the border between working time and personal time disappears. You never stop working or at least thinking about expanding your freelancing business.

Employment

The main advantage of having a “day job” is having a steady and predictable income. You sign a contract where you commit to working certain amount of time and you get stable and predictable salary. Since your employer is now responsible for finding tasks for you, you can stop thinking about your job when you leave the office at 5pm. You can also enjoy multiple benefits like: paid vacation time, paid sick days, health insurance, free gym subscriptions and so on. Employers usually do not offer such things to independent contractors. Those benefits you receive in exchange for having to work in certain time and space under a supervision and for a lower salary in comparison to what independent contractors receive.

How to be a good web developer?

Besides being simply good at your craft, there are few qualities that make a good web developer:

Team Player

Modern software developers almost never do work alone. You need to collaborate with other specialists from your team and with multiple people from your client’s side in order to make sure that all their goals are being met.

Hunger of Knowledge

Software developers never stop learning. New technologies, languages and paradigms are emerging on a daily basis and it’s your job to stay up to date. If you do not love the necessity of learning new things on a daily basis, you might face a burn out.

Patience

When doing web development or any other kind of software development, you need to be prepared for encountering multiple technical problems in the most unexpected places. Sometimes a lack of a single semicolon can break the most complex systems.

Reasonable Perfectionism

It’s absolutely crucial for developers to have this extreme attention to details. As stated earlier, even the simplest mistake can break the most complex website. On the other hand, you need to focus on delivering business value for your clients, so you can’t spend months on constant refactoring of you code and not focusing on new tasks.
