This organization contains a collection of backend services designed to explore the architecture, design, and implementation of modern distributed applications. Each repository focuses on a single service while emphasizing clean architecture, maintainability, and practical software engineering principles.

The goal is to build production-inspired services that can be developed independently and later integrated to demonstrate service-oriented architecture and backend system design.

This organization exists to:

• Build modern backend services using Java and Spring Boot
• Explore service-oriented and distributed architectures
• Practice API design and backend development best practices
• Understand communication patterns between independent services
• Develop production-ready engineering habits through focused implementations

Responsible for user authentication, authorization, identity management, and secure access to backend services.

Manages user profiles, account information, preferences, and user-related business logic.

Maintains product inventory, stock availability, inventory updates, and reservation workflows.

Processes payments and payment workflows while exploring transaction management, reliability, and idempotency.

Handles asynchronous delivery of notifications through channels such as email, SMS, and push notifications while exploring event-driven communication.

Projects within this organization emphasize:

• Clean Architecture
• RESTful API design
• Layered application architecture
• Testability
• Maintainability
• Security best practices
• Scalability
• Observability

Although each service is designed to function independently, they are intended to be integrated into a larger distributed system to explore:

• Service-to-service communication
• Event-driven architecture
• API gateways
• Containerization
• Orchestration
• Distributed transactions
• Monitoring and logging

This organization is an active engineering portfolio. Services are developed incrementally, with functionality, testing, documentation, and infrastructure expanding over time.
