Overview

SentinelTrack is a comprehensive fleet management solution designed to address real-world challenges in large-scale motorcycle rental operations. The system provides real-time tracking, intelligent reporting, and role-based access control to optimize fleet utilization and operational efficiency.

Key Challenges Addressed

Operational Scale

• Management of 150,000+ vehicles
• Distribution across 500+ parking facilities
• Support for 200,000+ active operators
• Year-over-year growth of 300%

Efficiency Improvements

• Reduces vehicle search time by 80% (from 15-20 minutes to under 30 seconds)
• Increases fleet utilization from 60% to 85%
• Decreases maintenance costs by 40% through predictive strategies
• Delivers annual operational savings of R$ 1.2M+

Features

Core Functionality

Fleet Management

• Real-time vehicle tracking and status monitoring
• Instant license plate search capabilities
• Comprehensive CRUD operations for motorcycles and parking facilities
• Advanced filtering and search mechanisms

Analytics & Reporting

• Real-time operational dashboards
• Fleet utilization metrics
• Maintenance scheduling and tracking
• Performance KPIs and trend analysis

Security & Access Control

• Spring Security integration with role-based authorization
• Three-tier access model (Admin, Manager, Operator)
• JWT-based API authentication
• Session management with automatic logout

API Integration

• RESTful APIs with comprehensive documentation (Swagger/OpenAPI)
• Mobile-optimized endpoints
• Health check and monitoring capabilities
• CORS configuration for cross-origin requests

Technology Stack

Backend

• Java 17 - LTS version with modern language features
• Spring Boot 3.4.5 - Production-ready application framework
• Spring Data JPA - Data persistence layer
• Spring Security - Authentication and authorization
• Flyway - Database migration management
• Thymeleaf - Server-side template engine

Database

• H2 - In-memory database for development
• Oracle - Production-grade database

DevOps & Tools

• Gradle - Build automation and dependency management
• Docker - Containerization
• GitHub Actions - CI/CD pipeline
• Swagger - API documentation

Testing

• JUnit 5 - Unit testing framework
• Mockito - Mocking framework
• AssertJ - Fluent assertions

Architecture

SentinelTrack follows a layered architecture pattern with clear separation of concerns:

┌─────────────────────────────────────┐
│     Presentation Layer              │
│  (Controllers, Views, DTOs)         │
└─────────────────────────────────────┘
              ↓
┌─────────────────────────────────────┐
│     Application Layer               │
│  (Services, Business Logic)         │
└─────────────────────────────────────┘
              ↓
┌─────────────────────────────────────┐
│        Domain Layer                 │
│  (Entities, Repositories)           │
└─────────────────────────────────────┘
              ↓
┌─────────────────────────────────────┐
│    Infrastructure Layer             │
│  (Database, Security, Config)       │
└─────────────────────────────────────┘

Design Patterns

• Repository Pattern - Data access abstraction
• Service Layer Pattern - Business logic encapsulation
• DTO Pattern - Data transfer optimization
• Dependency Injection - Loose coupling and testability
• Builder Pattern - Complex object construction

SOLID Principles

• Single Responsibility - Each class has one well-defined purpose
• Open/Closed - Open for extension, closed for modification
• Liskov Substitution - Subtypes must be substitutable for base types
• Interface Segregation - Client-specific interfaces
• Dependency Inversion - Depend on abstractions, not concretions

For detailed architecture documentation, see ARCHITECTURE.md.
