SoulSync Backend is a RESTful API server that powers the SoulSync matchmaking platform, handling authentication, real-time communication, user data, and media uploads.

It is designed for scalability, security, and real-time interaction.

This project was developed for JS Club – Japanese Software Engineers.

• RESTful API architecture
