How to become a Full Stack Developer

6 minute read

A Full Stack Developer is someone who works with both the front and back ends of a website or application.

Front-end developers work on what the user can see (such as the finished product of an app), while back-end developers build the infrastructure that supports the app. 

These professionals are a valuable addition to any digital team, because instead of bringing in a separate Front-end and Back-end Developer, a Full Stack Developer fills the role of both. 

If this is a career you’re thinking about pursuing, you no doubt want to know how to become a Full Stack Developer. It’s worth having a read of our blogs ‘The top tools budding Full Stack Developers should know’ but also, below we cover everything you need to know.

Why become a Full Stack Developer?

Technology is rapidly evolving, which is great but the issue this poses for many businesses is that they can’t afford to hire a full team of developers.

Full Stack Developers offer the perfect solution because they work with the design aspect of software that clients interact with, as well as the coding and structuring of the server end. 

Demand for these professionals has further increased in response to the coronavirus pandemic as it has become almost essential for organisations to migrate their business to a virtual world.

In March 2020, the UK did in fact see a 10% increase in jobs posted for Full Stack Developer roles. 

Aside from being in-demand, there are a number of other benefits drawing people to this role including: 

  • Competitive salary which continues to increase with experience 
  • Variety – you could be working on different projects from week to week 
  • Plenty of opportunities to learn new skills
  • The role is constantly evolving as technology progresses

What are the day-to-day responsibilities of a Full Stack Developer?

Full Stack Developers get involved with projects that range from the initial planning phase to building user-facing websites. 

Despite what the job title suggests, you don’t necessarily have to write all of a site’s code yourself. Many Full Stack Developers spend the majority of their time in either the front or back end of a site.

They do however know enough about coding that they can jump in anywhere if needed. If you’re a freelancer or the only developer working on a project, you may be responsible for coding entire websites. 

Your day-to-day responsibilities may include:

  • Using a range of technologies and languages to develop applications (such as JavaScript or HTML)
  • Assisting with the design and creation of software
  • Testing and fixing bugs and other coding issues 
  • Developing and managing databases and applications
  • Writing effective APIs
  • Troubleshooting, debugging and upgrading software
  • Creating security and data protection settings
  • Building websites and applications with a mobile responsive design
  • Working with other members of the digital team to improve software

  • Knowledge of security concerns and best practices
