About the project
How often do your friends call and say “Hey, where are you?”. The application Spots has created, that would always know where your friends are and to let friends know where you are. If you come in another city or country, then your friends will immediately recognize it through the app. Also, you can see what your friends are doing or what they think about and in what mood they are. In this, they are helped by a very simple system of statuses.
The first version of the app was made in Java (Spring), but the app became very popular among users and the current platform could not get the increased load. We have decided to rewrite the backend NodeJS (Express) and use VoIP technology to facilitate queries. All these actions gave the increase of productivity by 3 times. Now, this app is used by more than 10000 users and application easily cope with this load.View project’s website
