A career in full-stack development can be a really exciting and gratifying career path, providing many opportunities to upskill and find your niche within the different areas of tech. Full-stack development plays a key role within software development that requires professionals who will be able to work both on the front-end and back-end development of a website, application or software – which we will look into more depth below. If you are interested in getting started or shifting your career into this field, then here is our top guide for becoming a full-stack developer.

A full-stack developer (FSD) is a versatile team member, proficient in both front-end and back-end development and capable of working on all aspects of a web application or software. They are responsible for writing, testing, and maintaining high-quality code, collaborating with a team, and addressing various stages of the software development life cycle. 

Full-stack developers handle tasks ranging from

  • Designing user interfaces
  • To develop server-side logic
  • Managing databases

Essentially they are contributors to creating innovative and functional technology solutions.


Full-stack developers are expected to become proficient in front-end technologies, including JavaScript, HTML, and CSS. As well as back-end languages and frameworks such as Python, Node.js, etc.

Full-stack developers must be highly capable of working with databases and server-side architecture and have a strong understanding of version control systems and deployment processes.


Full-stack developers will encounter an array of coding languages during their careers such as those mentioned below

Front-End Developer 👉

A front-end developer focuses on a website or an application’s user interface and user experience – which includes layouts, navigation and interactive elements. They are responsible for designing and implementing visual features of the application that are usually client and user-facing. So developing an eye for detail and design is a helpful trait to have in this role. 


Are you proficient in 

  •  HTML
  • CSS
  • And JavaScript?

Are you familiar with front-end frameworks/libraries like

  •  React
  • Angular
  • And Vue.js?

Do you have a developed understanding of responsive design principles?

  • Are you able to collaborate with UI/UX designers to implement design specifications?

Back-End Developer 👈

 A back-end developer, on the other hand, focuses more on the server side of an application which includes managing databases, server logic, and ensuring the smooth functioning of the applications.

They are responsible for ensuring security and performance on the server side, integrating databases to store and retrieve data. As well as developing server-side logic and APIs (applications programming interfaces) that handle data processing, user authentication and other server-related tasks.


  •  Are you experienced in a back-end programming language, such as
    • Java
    • Python, 
    • PHP, etc.?
  • Are you familiar with back-end frameworks such as
    • Express.js
    • Django
    • Flask
    • Ruby on Rails, etc?

  • Experience with server deployment and optimisation? 

Full-stack development 👉👈

Full-stack brings the best of both worlds in development together! Full-stack developers have expertise across both front-end and back-end development, meaning they often have to be pretty well-versed and agile in both areas. In a team scenario, different individuals within these three roles often collaborate closely to build fully functional web applications.

The career path of a developer in tech can follow a trajectory that includes various levels of expertise, responsibilities, and potential specialisations (we’ll touch on that shortly!). To have a long and fulfilling career, we always encourage you to take on new learning opportunities and challenges at various stages in your journey.



  • Entry-Level Developer
  • Intermediate Developer / Software Engineer
  • Senior Developer / Senior Software Engineer
  • Lead Developer / Tech Lead
  • Engineering Manager / Development Manager
  • CTO (Chief Technology Officer) or VP of Engineering

Entry-Level Developer

These are often referred to as ‘Junior Developers’ or may even start as Software Engineers by gaining hands-on experience and exposure to the development environment. They get involved in code implementation and apply these to smaller tasks and best practices. At this stage, proficiency in foundational programming languages and frameworks would be an essential skill to have as you get started. 

Next Steps to level up ☝️Focus on improving coding skills and problem-solving abilities such as through hackathons or mini-coding projects. We recommend trying out or MOOCs which will allow you to collect knowledge on different tech topics as an entry-level developer, to test out the waters and discover strengths and weaknesses. 

Intermediate Developer

As developers gain experience, (or for some more seasoned software engineers) they will move into more intermediate roles, where they take on more complex tasks and contribute to larger projects. This involves being more hands-on with a larger portion of projects, mentoring junior developers, and collaborating with other team members around architecture and design decisions. 

Next Steps to level up ☝️This would be a great time to start considering what areas you would like to specialise in, whether you want to stick with either front-end or back-end. Perhaps you’d be interested in mobile development? Or maybe you like being an all-rounder and continue levelling up in full-stack! At this stage, learning is key and pursuing advanced training and certifications like with our Kickstarter Classes and even the CFGdegree, can really boost your prospects in higher-level roles.

Senior Developer

Senior Developers will take on more leadership roles within development teams, so a lot of the day-to-day tasks may involve collaborative projects. They’ll also be contributing to strategic decision-making and leading project development. With their in-depth knowledge of technology stacks, comes opportunities to take on mentorship with both junior developers and engineers within the teams.

Next steps to level up ☝️At this point in your career, there are opportunities to specialise in more niche and emerging technologies such as machine learning and artificial intelligence, as well as pursue further leadership learning or management positions.

We interviewed our colleague Robyn McClelland who graduated from the CFGdegree in 2024! This is what she said

“The coolest thing about the CFGdegree program has got to be how it mixes learning along with the instructor and then working on real work-life challenges. It’s not your typical degree where you just sit in lectures all day, you dive into hands-on projects from the start! 

Whether we’re building databases, building apps on React, or cracking the code to integrate new applications using API, every day brings something new and exciting. The best part? Learning from pros who’ve been there, done that, and are still trailblazing in their fields.

The best part of graduation is the build-up. The excitement of the big day, where we’ll celebrate all the late nights, the breakthroughs, and the friendships made along the way.

Stepping onto that stage, surrounded by cheers and decked out in cap and gown, it’s a moment to remember. It’s not just about closing the books on this chapter; it’s about the journey for whatever comes next, armed with the skills and experiences that CFGdegree has given me.”
