The junior developer portfolio: six things employers look for

When reviewing applications for junior roles, recruiters and engineering managers usually spend just a few minutes on each one. In that time, what your portfolio says matters more than your CV. We have gathered the six points most emphasised in our conversations with our employer advisory board.

1. Fewer, finished projects

Three projects that work and can be seen live are far more effective than ten half-finished ones. Every project should have a live link or a short demo video.

2. A good README

Briefly explain what the project does, what problem it solves, the technologies used, how to run it and the challenges you faced. The README is the first thing an engineering manager reads before opening the code.

3. A clean commit history

Small, meaningful commits instead of messages like “final version” or “fix 2” show how the project evolved and how you work. One giant commit uploaded at once leaves employers with questions.

4. Some tests

Comprehensive tests are not expected at junior level, but a few unit tests for critical functions and one end-to-end test show that you care about quality. A simple CI pipeline that runs the tests automatically is an extra plus.

5. Evidence of teamwork

Pull requests, code review comments and task tracking in a team project show concretely how you would work in a team. That is why bootcamp team projects are an important part of the portfolio. State your own contribution clearly in the README.

6. Your own idea

Instead of the to-do list or weather app everyone builds, a project that meets a real need sticks in the mind: order tracking for a local shop, volunteer planning for a charity, or a map built with your city’s open data. A project with a story to tell in the interview sets you apart.

Common mistakes

The mistakes we see most often in portfolios are broken live links, files containing passwords or API keys uploaded to public repositories, and careless descriptions mixing languages. Before applying, click every link, move secrets into environment variables and write your READMEs carefully in one language. Do not forget to pin your three best projects on your profile page.

Code written with AI

Writing code with AI-assisted tools is now common in the industry. Employers expect you to understand and be able to explain the code when you use these tools. If an interviewer asks why a function in your portfolio is written the way it is, you should be able to answer clearly.
