When you’re early in your tech career, it’s easy to feel like you’re stuck in a loop: “I need experience to get hired, but I need to get hired to get experience.”
This is where side projects come in.
Whether you’re a recent graduate, self-taught developer, or transitioning from another industry, side projects are one of the most powerful ways to show what you can do. They give hiring managers something real to look at, and show that you’re proactive, curious, and genuinely interested in tech beyond the classroom or bootcamp.
Here are the kind of side projects that can make a strong impression:
Building Something You’ll Actually Use
Hiring managers love to see personal projects with purpose. Built a budgeting app to manage your own finances? Created a simple tool to help your friends plan a holiday? Even if it’s small, it shows initiative and problem-solving.
Tech used matters – but what’s more important is why you built it.
Contribute to Open Source
You don’t need to overhaul a massive library. Even small pull requests, bug fixes, or documentation updates count. It shows you know how to collaborate, read other people’s code, and work with version control tools like Git.
It also gives you a chance to reference your contributions during interviews, something most candidates skip.
Recreate a Real Product
Pick an existing app (like Twitter, Spotify, or Trello) and build a simplified version of it. This shows that you understand how common features work and can replicate them independently.
Bonus points if you add your own twist – like dark mode, improved layout, or a feature you wish the real app had.
Make a Portfolio Site (But Make It Interesting)
Every dev seems to have a portfolio site, but many of them are basic. Use yours to tell a story. Include interactive elements, explain your projects, and show some personality. It’s your chance to show both your skills and your communication style.
Think of it less like a CV and more like a pitch – why should someone hire you?
Automate Something Boring
Did you build a script that renames and organises files for you? Scrape product prices and track them over time? Hiring managers love to see real-world automation, especially if you can explain the problem you solved.
Practical + Clever = Memorable.
Work With Data
Even if you’re not in a data role, building a dashboard or visualisation can show off your analytical thinking. Try using public datasets (e.g. from Kaggle or data.gov.ie) to create something useful or interesting.
Data cleaning, analysis, and presentation are valuable skills across a lot of tech roles.
You don’t need a long list of professional experience to stand out; you just need something that shows your potential. Side projects tell hiring managers you’re not just waiting for the perfect job to fall into your lap. You’re building, learning, and already acting like someone who belongs in tech. And that’s exactly what employers want to see.
