Intiva Platform

This API is made with Java, Spring Boot and Spring Data and MongoDB persistence. It also uses Spring Security and JWT for authentication and authorization.

Summary

This application is a backend API for the Intiva Platform, which is a platform for managing expenses, savings and incomes. So, it includes the following features:

• Transaction management: Register and monitor all transactions, including expenses and incomes.
• Categorization: Classify transactions into different categories for better organization and analysis.
• Budget management: Set and track budgets for different categories of expenses and for different periods of time.
• Savings management: Set and track savings goals, and monitor progress towards those goals.
• Reminders and notifications: Set up reminders for upcoming bills, budget limits, and savings goals, and receive notifications to stay on track.
• Family group management: Create and manage family groups to share expenses, budgets, and savings goals among family members.
• Reporting and analytics: Generate reports and visualizations to analyze spending patterns, savings progress, and overall financial health.
• User management: Manage user accounts, including registration, authentication, and authorization.

Technologies Used

For the development of this API, the following technologies were used:

Main Stack

• Java 21: The programming language used for the development of the API.
• Spring Boot: A framework for building Java applications, used to create the API.
• Spring Data: A framework for data access, used to interact with the MongoDB database.
• PostgreSQL: A relational database management system, used for storing data in the application.
• Redis: An in-memory data structure store, used for caching and improving performance of the application.
• Spring Security: A framework for securing Java applications, used for authentication and authorization.
• JWT (JSON Web Tokens): A standard for securely transmitting information between parties, used for authentication and authorization.
• Swagger: A tool for documenting and testing RESTful APIs, used to create API documentation and provide an interface for testing the API.

Testing

• JUnit: A testing framework for Java, used for unit testing the API.
• Mockito: A mocking framework for Java, used for creating mock objects in unit tests.
• Spring Test: A framework for testing Spring applications, used for integration testing the API.

Approaches and Patterns

• RESTful API: The API follows REST principles for designing the endpoints and interactions.
• MVC (Model-View-Controller): The application is structured following the MVC pattern.
• Domain-Driven Design (DDD): The application is designed using DDD principles, focusing on the core domain and its logic.
• Layered Architecture: The application is organized into layers, such as the domain layer, infrastructure layer, application layer, and interfaces, to separate concerns and improve maintainability.
• Test-Driven Development (TDD): The development process follows TDD principles, where tests are written before the implementation of the functionality.

Documentation

The project includes basic documentation and is available in the docs folder. It includes:

• C4 Model Software Architecture Diagrams: includes context, container and component level diagrams to provide an overview of the system architecture and its components.
• Class Diagrams: includes class diagrams to illustrate the structure of the codebase and the relationships between classes.
