Online-Shop >>> Backend Template
This is a Backend application written by me as a template for future online store projects. Extensive customization of interrelationships of different entities using JPA / Hibernate allow to improve this system flexibly and quickly. Implemented Spring Security. Has RBAC system that allows you to protect sensitive information. Introduced authorization system that supports 3 roles:

1) Admin,

2) Moderator,

3) Customer.

For additional protection - introduced mail confirmation system during registration. Tokens for mail confirmation are limited in time and become unavailable after expiration.

Back-end stack: Java 17 , Spring Framework, PostgreSQL, JPA
