Have you ever been to an event but later realized you only remembered half of the people you met? Constellate was made to help you keep track of who you meet and where by displaying notes about each person, what you talked about and other custom notes. Constellate is as a decoupled app with a Java back-end and Ionic/Angular front-end. Developed at Galvanize in a two-person team. The Java backend handles authentication, persists user data with a postgres database, and serves it to the mobile app. The mobile app is made using Ionic framework.
