Many people struggle with finding the time for over-ambitious side projects. I developed Collab to solve this problem. It’s an app that makes finding people to work with on side-projects easy. It was built as part of my A-Level computer science coursework and features post creation, realtime messaging and group chats. The entire app is powered by the Firebase realtime database and Firebase storage.
