What Is a Full-Stack Developer?

A full-stack developer is a developer or engineer who can build a website's front and back end. The front end (the parts of a website a user sees and interacts with) and the back end (the behind-the-scenes data storage and processing) require different skill sets. Since full-stack developers are involved with all aspects of the development process, they must have expertise in both.

A full-stack developer can work in-house or at a computer development company that engineers websites, software, and other components for other businesses.

What does a full-stack developer do?

Full-stack developers design and create websites and applications for various platforms. A full-stack developer’s job description might include the following:

• Develop and maintain web services and interfaces

• Contribute to front-end and back-end development processes

• Build new product features or APIs

• Perform tests, troubleshoot software, and fix bugs

• Collaborate with other departments on projects and sprints

The world of full-stack development is large, and many new and evolving technologies continually push the limits of what a full-stack developer can create. Staying on top of cutting-edge technology and techniques in the full-stack development field is one of the many exciting aspects of working in this role. 

Full-stack developer skills

Full-stack developers may be creative, graphically inclined, internet- and tech-savvy, and attentive to detail. You’ll want to learn the following skills to have a career in full-stack development:

• Front-end development is the process of creating a website's interface. It entails coding details like drop-down menus, fonts, colours, and page layouts. Full-stack developers should also know how to work with front-end technologies like HTML and CSS and scripting languages like JavaScript to make websites and applications visually viable and appealing. If you want to transition into full-stack development from back-end development, you might consider earning a Professional Certificate in front-end development from an industry leader like Meta.

• Back-end development skills entail using back-end programming languages like Python, PHP, Ruby on Rails, and CakePHP and understanding how algorithms and business logic work. You can enhance your back-end development skills to prepare for a full-stack developer role with Meta's Back-End Developer Professional Certificate.

• Web design includes using software such as Photoshop to create and design graphics and themes. It’ll be helpful to familiarise yourself with basic UI (user interface) design principles to help you create navigational elements, backgrounds, and audio and video elements.

• Database management skills are required for full-stack developers, though they are also part of the skills needed for back-end web development. A full-stack developer should be able to design, understand, and manipulate database queries and web storage.

As a full-stack developer, you may need to know your way around some of the following programming languages and tools:

• Angular JS

• Apache HTTP Server

• AWS

• CSS

• Ember.js

• JavaScript

• jQuery

• Laravel

• Microsoft SQL Server

• MySQL

• Nginx

• Node.js

• PHP

• Polymer

• React

• Ruby on Rails

Why pursue a career in full-stack development?

A career in full-stack development combines creativity with analysis. As such, you’ll have plenty of opportunities to learn and implement innovative principles in your work.

Average salary and job outlook

According to Indeed [1], the average annual salary of a full-stack developer is £53,663 as of October 2024. This figure does not include bonuses, commissions, or other additional payments that may be offered to a full-stack developer annually. 

The job outlook for full-stack developers is bright. Companies and organisations across the UK and the globe require an online presence in nearly every industry, opening opportunities for full-stack developers to build and maintain websites. Furthermore, smaller businesses hire full-stack developers over front-end and back-end developers to spread their resources further. 

How to become a full-stack developer

Consider earning a degree.

Many employers, although not all, require their software engineers to have a university degree in software engineering and relevant technical knowledge [2]. Full-stack developers typically study computer science, computer engineering, or a related field. A degree can hone the technical and workplace skills necessary to be an effective full-stack engineer. 

Research entry-level roles. 

There are various levels of full-stack development jobs. Search job sites for junior or entry-level positions to understand what skills employers are looking for in applicants. 

Develop your coding skills. 

To be an effective full-stack developer, you should acquire and continue upgrading your knowledge of applicable programming language skills. Consider taking courses in relevant languages like Python, HTML, CSS, and Javascript. 

Build a portfolio.

Releasing your skill set on a resume can be challenging without hands-on experience. A portfolio shows potential employers what you’re capable of by highlighting your best work. Gather projects you’ve completed through coursework or previous jobs. Include screenshots, and describe the technologies you used and your role in each. 

Practice technical interview questions.

Interviews for tech-related roles often include a technical portion. During this part of the interview, you may be asked to complete a live coding exercise, design challenge, or take-home assessment.
