spring boot restful api for user and customer management

We propose the development of a Spring Boot application that provides user management functionalities such as user registration, email verification, two-factor login, client credentials generation, token generation, and customer data management operations like upload, update, delete, view, and search. The application aims to facilitate secure and efficient user management while allowing seamless management of customer data.

Technology Stack:
The proposed application will be built using the following technologies:

Spring Boot: A powerful Java framework for building robust and scalable applications.
Spring Security: To handle user authentication, authorization, and session management.
Spring Data JPA: For database interactions and managing customer data.
PostgreSQL (or any other preferred database): To store user details and customer data.
Java Mail API: For sending email verification links to users.
JSON Web Tokens (JWT): To generate and manage authentication tokens.
