Hackathons

Learn new skills, meet new people, and have fun!


Why Join Hackathons?

Imagine developing an amazing application in just a few days. By yourself? That’s nearly impossible! But with many other eager developers in an organized forum? This is commonplace! It’s called a hackathon; a marathon in software development. Many hackathons involve development team; which means you create an even better application and improve your teammwork along the way! Futhermore, throughout the development you are sure to learn new software skills. If you enjoy software development (as you should), hackathons will be a ton of fun! Lastly, you could win a prize if your application is really good! So join one of the hackathons below. You won’t regret it!
