🎟️ Event Registration System

A full-stack Event Registration System built using Python, Flask, REST APIs, SQLAlchemy, MySQL/MariaDB, HTML, CSS and JavaScript.

The system allows users to view available events, check event availability, register for events, and receive a unique registration number and registration code.

This project was developed as part of my Backend Development Internship to gain practical experience in REST API development, database management, backend validation, and frontend-backend integration.
