Technical Description & Role

This was a key project simulating a complete medical booking system. The main challenge was designing a complex relational database (MySQL) and building a secure, multi-role API (Spring Boot).

Designing the database (ERD) including tables for: Patients, Doctors, Appointments, Specialties, Invoices, etc.
Assigning tasks to 3 team members, and reviewing code on GitHub before merging into the main branch.
Leading the development of the API, database, and integrating **Spring Security** for role-based authorization (ADMIN, DOCTOR, PATIENT).
Building RESTful APIs (using Spring Boot) for all CRUD functionalities.
