While you might have these skills, without a portfolio, it’ll be nearly impossible for you to get a job in website development. Building backend projects for your developer portfolio can help bridge the gap between what you know and what you can actually do. That’s exactly what potential employers want to see.

While front-end developers build the look and feel of a website, backend developers work behind the curtain. They build features like data storage, security, and other functions invisible to the average user.

The backend developer works on server-side software. Therefore, they ensure that the website or application works correctly. Their work requires a knowledge of the following:

  • Coding using a programming language like Python, Java, Ruby, and PHP.
  • Frameworks like Laravel, Ruby on Rails, Django, and Node.js.
  • Data structures and algorithms.
  • HTTP and the basics of the web.
  • SQL and other database fundamentals.
  • Web servers like Apache, NGINX, Lighttpd.
  • Web deployment and security.

A successful backend project for a developer’s portfolio must show off at least one or two of these skills.

You may know how to build the back end of applications. But if you’ve only worked on front-end projects in prior roles, you’ll need to prove your ability to transition. Backend projects can help you demonstrate your skills and make the switch.

Why Your Portfolio Needs Backend Projects

If you know all about databases, coding, and the other skills listed in the section above, you might think you don’t need projects in your portfolio. However, this mindset can lead to rejected applications and frustration.

Here are some reasons why your portfolio needs backend projects.

1. Backend projects prove your technical ability.

Suppose you are a self-taught developer who went through several tutorials and built a few projects based on these sessions. In that case, you might be even more frustrated when you keep getting rejections from employers despite including these projects in your resume.

While useful, these tutorial projects are not likely to impress anybody looking to hire a backend developer. Why not? Because they only show two things:

  1. That you are just a learner. The ideas you likely worked on in your tutorials already had a solution. Thus, you were probably only following along with the tutor. While it’s great in a learning environment, this doesn’t transfer to a work environment where solutions aren’t available.
  2. The code you created for the tutorial’s project might be copied or not — recruiters don’t know the difference.

An independent, backend project can solve these challenges. These original works show that you have both the coding and problem-solving skills to excel in a backend developer role.

2. You can advertise your skills.

Resumes are usually enough to start applying for jobs. However, resumes only show what you claim you can do.

A portfolio linked to your social media handles on Twitter, Facebook, or LinkedIn will let your contacts and potential recruiters see the full scope of your ability. There are many examples of people who got contacted by top companies based on their portfolio's strength.

Now that you know the importance of a portfolio, let’s dive into how you can demonstrate your skills.
