Fullstack developer in front of computer

Are you considering learning web development skills? Perhaps you’ve always heard about full-stack development and wondered how you could become a full-stack developer.

Full-stack developers are web developers who develop both the front end and back end of websites and applications. They are familiar with JavaScript, HTML, CSS, Python, and other coding languages.

They are very common in the tech industry, and as technology requirements increase, particularly in businesses – the need for skilled full-stack developers increases. According to a survey conducted by Stack Overflow in 2020, more than 54% of working technologists consider themselves full-stack developers, 37% call themselves front-end developers, and 55% consider themselves back-end developers.

Full-stack development is a profession that stands out in the tech industry for its multifaceted nature; it is a holistic engineering practice that evolves to all aspects of web development. However, with the rate at which tech advances, the rate at which companies hire remotely, and with tech companies worldwide continue to hire for more talents, there has not been a better time to start a career in web development.    

What Does Full Stack Mean?

Full-stack means the collection of technologies and systems required to execute a project. The majority of software consists of two major elements; the front-end, which users see and interact with online, and the back-end, where the codes and databases work in the background to collect data, i.e., behind the scenes of the website and app.

Full-stack means an advanced programmer possesses functional knowledge and experience in all the software creation components. Web developers can work behind the scenes, writing robust code that runs on some of the applications and programs you use each day.

However, a full-stack developer can oversee every part of a project, including databases and servers to systems and clients. They also work at the front-end of the software creation process, evaluating and tweaking the software’s user-friendliness.

A full-stack developer is expected to evaluate and understand how each component of a project works together while understanding how the front-end and back-end will communicate with each other. In recent years, web development has become more complex, and there are several job opportunities in the industry for developers with different skills.

This means that you are either a front-end developer, a back-end developer, or a full-stack developer in web development. Thus, as a developer, you will be classified depending on your skill-set.

  1. Front-end development – developers who deal with what the users can see and interact with
  2. Back-end development – developers deal with what users can’t see or interact with on a website and app.
  3. Full-stack development – developers can do both front-end and back-end development, which applies to both app and website.

However, to understand further the roles above, it’s essential to understand the skills and knowledge needed to begin a career in web development.

Education and experience are the best ways to learn to become a full stack developer

They perform everything in developing a website or application from start to finish, and they have the knowledge, experience, and proficiency with both ends of a website and applications.

What Is a Full-stack Developer?

A full-stack developer is not an average web developer with only front-end or back-end skills but they can have front and back-end technologies and an in-depth understanding of web architecture.

A full-stack engineer is an expert who deals with front & back end development, technical jobs, databases, and the ability to develop application programming interfaces. They are developers who work on the full stack of software. 

They are sometimes called “jack of all trades” developers. They perform everything in developing a web-based application from start to finish, and they have the knowledge, experience, and proficiency with both ends of a website and applications.

They are essential in every part of website development projects. Full-stack developers help bridge the gap between the client-side and server-side of a site. This ensures that a website is both appealing and functional.

Typically, a full-stack engineer has a grasp of client-side technologies such as CSS, JavaScript, AJAX, and server-side technologies such as hypertext preprocessor (PHP) and Ruby.

However, being a full-stack engineer doesn’t automatically mean a full-stack engineer is responsible for writing all the code. Still, they can do so if they wish and have the skills required to jump into any part of the web and application development project as needed.  

Some of their core responsibilities include: testing for a bug in code, developing and designing user relations, creating solutions to project requirements, modifying code, using hardware and software, creating databases and servers, cross-platform optimization, and a lot more. 

The Front-end

Almost everybody is online these days. The internet facilitates interpersonal communication between users through platforms such as email and social media. Still, it’s now much more relied upon since everybody goes online and sources all kinds of information.

Most online applications have an area where users can interact. When you land on a website; you are greeted by the welcome page, menu, services page, blogs, articles pages, and other items that facilitate navigation and utility.

All of these web pages fall under the term “front end.” The front end includes a user interface which is the part of the application or website designed for users to see and interact with.

Front-end Developers

A front-end developer is also called a front-end web engineer. A front-end web developer is a professional who is responsible for creating and implementing the user interface as well as the application appearance and basic design. Consumers require this interface so they can access and interact with the website or application.

However, they ensure that their design works online using usability testing and coding languages such as JavaScript, HTML, Java, and CSS.

Front-end Developer Roles and Responsibilities

Perhaps you may be wondering what a front-end web developer does?

They decide web page development and structure and develop features to improve the user’s experience. They also ensure that a website is smartphone-capable, builds reusable code for future use, and provides a well-optimised website for speed and scalability.

Lastly, web developers use different coding languages to design and develop web pages, such as CSS, JavaScript, and HTML.

You can learn such languages by taking courses on front-end web development, learning the command line and version control, improving your skills, and practicing at all times.

Above all, the future looks bright for a professional, inexperienced, or beginner who wants to become a front-end web developer.

According to the United States Bureau of Labor Statistics (BLS), web developer employment which includes front and back end web developers in the United States, is projected to increase by 15% from 2016 to 2024.

Back-end Developers

A back-end developer, also known as a back-end web developer, creates and maintains the tech to operate a website properly. Back-end developers use a database, application programming interface, and other behind-the-scenes systems. 

A back-end web engineer is a skilled and professional software developer who understands, plans, designs, creates, and tests the back-side and business logic of an application. They build and manage the back-side applications and websites that users don’t see or interact with directly but do everything possible to make the front end of applications and websites appealing.

As front-end developers build the web pages and forms that users see and interact with, the back-end developer manages and controls the behind-the-scenes engines of applications and websites.

Back-end Developer Roles and Responsibilities

Back-end engineers collaborate with front-end and full web stack developers to build comprehensive digital solutions for business needs. They work hand in hand to ensure that applications or websites are scalable and appealing when hit by significant traffic or demanding programs.

However, some of the back-end web developer responsibilities include creating and maintaining web applications, evaluating the efficiency and speed of present applications, writing high-quality code, working with QA developers for software testing, troubleshooting, debugging, and more. To get started, it helps to learn Python, PHP, Ruby, SQL, REST, and SOAP.  

Back end developers focus on the server-side
