What is a Full Stack Developer: Required Skills and More in 2023

What is a Full Stack Developer?

Full-stack technology refers to the entire depth of a computer system application, and full stack web developers are those who are capable of developing both the front end and the back end of web development. All of the features that are visible to the client, or the viewer of the site, are included in the front end.

  • Programming a browser (By using JavaScript, jQuery, Angular, or Vue)
  • Programming a server (By using PHP, ASP, Python, or Node)

Let’s say you’re using your Instagram application. Every time you refresh, new content is loaded on your screen. You can like a picture, add new ones, search for profiles and do so much more. Although it provides a seamless user experience, there’s a lot that goes on in the backend. HTTP requests are made to the Instagram servers to retrieve and load information. This is facilitated with the help of backend frameworks. 

Typically every application consists of the front-end, the backend, and the database. 

A Full Stack Developer is associated with the creation of an application from its start to finish. He designs the front-end and the backend of an application while ensuring its efficiency, reliability, and other crucial features. 

Client Software (Front End) vs. Server Software (Back End)

Client Software (Front End)

Front-end development is programming done on the front end of a website – the part that people view and interact with. Front-end developers are in charge of the complete user interface as well as the application’s aesthetic design. Front-end developers are critical in ensuring that users have a good experience every time they browse a site since websites are more effective when they appear professional and work efficiently. Front-end developers typically employ CSS3, JavaScript, and HTML because these languages are essential for website design. Some of the languages used are mentioned below.

Server Software (Back End)

If the front end of a website is the user interface and navigation, the back end is the nuts and bolts. It makes no difference how well a website looks or functions if it lacks content. PHP, Python, and CSS are some of the most popular languages for back-end programming.

PHP is frequently used in conjunction with SQL to build online databases. The front-end HTML files use information obtained from this database. Every time you update your social media profiles or read the news, you are probably engaging with these languages without even realizing it. A database becomes more important as the amount of information saved on a website grows. 

Skills of a Full Stack Developer

Now that you know what a full stack developer does, let’s look at the skills required to become one. 

Front-end Languages and Frameworks

HTML and CSS

HTML short of Hypertext markup language governs the appearance of text/images on the screen. It formats the text as headings, paragraphs, pop-ups and so on. It typically consists of tags that give a different meaning to the text in a document structure.

Backend Technologies and Frameworks

  • JavaScript and its environments like NodeJS and ExpressJS. Node is an open-source, cross-platform runtime environment that allows developers to create server-side tools and JavaScript applications. Knowledge of the basic command line like npm (Node Package Manager) is essential.
  • Java, in particular, was built from the ground up to be run on the server-side. Popular Java frameworks include Spring and Java Server faces. 
  • Python is the most popularly used language. It is flexible and easy to use. We use Python frameworks like Django and Flask for backend development. Django is a high-level Python web framework that enables rapid development of websites. It is free and open-source, has a huge and active community of users.
  • C# language is for many the most preferred architecture when it comes to backend programming in Windows environments.
  • Other languages include PHP, Perl, and Ruby.

Database Management Systems

A full-stack developer writes code that is used to perform Relational mapping to fetch data from the database. Some popularly used DBMS are MySQL, SQL SERVER and PostgreSQL, MongoDB, and Oracle Database. A good understanding of their workings is critical. 

Version Control

Version control systems help manage the project files and keep track of the entire history of the user’s things. Popular ones are Git, Github, and Subversion.  

Git helps manage the project files. It keeps track of the entire history of things that the user is working on. GitHub is a web-based service for version control using Git. The user can look at other people’s code, identify issues or errors, and even propose changes. 

Web Hosting Platforms

Web hosting platforms allow you to deploy your product on a cloud service provider so we can access it from the WWW. Popular ones are Amazon web services, Google cloud platform, Heroku, and Microsoft Azure.

Soft Skills 

A full-stack developer needs to possess some basic soft skills as well. 

  1. Creativity – The developer must understand the project’s objectives and create a product that engages the target audience. 
  2. Strategic planning – Planning is a critical phase in any development life-cycle. The developer should possess the aptitude to plan the design, development, and implementation phases strategically. This helps streamline the process.
  3. Analytical skills – As the name suggests, these skills help analyze information accurately and make logical, data-driven decisions that help in maximizing efficiency. Now, these are skills that one develops when they’re exposed to it. But a good sense of understanding is required. 
  4. Problem-solving skills are again crucial to predict any errors and develop a bug-free application. From a business perspective, problem-solving skills play a significant role in ensuring the smooth conduction of tasks. 
  5. Time management skills – The developer must meet the deadlines while ensuring proper execution of his tasks.

Now that you are familiar with the skills, let’s look at the key responsibilities.
