I built an open source event-management system

In plain words

An open source event-management system designed for developers who need to organize and coordinate events. The system provides tools for creating events, managing attendees, and handling scheduling. Launched in 2018, the project is available on GitHub for developers interested in contributing to or customizing the platform for their own event needs.
