Case Study

Resort Management System

Backend system for managing resort bookings, operations, and secure access with clean APIs and structured workflows.

.NET 8 ASP.NET Core Clean Architecture PostgreSQL JWT Auth

Problem

Resorts require a centralized backend system to manage bookings, guests, and internal operations reliably. Existing workflows were fragmented, difficult to scale, and lacked proper access control.

The system needed to support multiple operational workflows while ensuring data consistency, secure access, and future extensibility.

My Role & Responsibilities

• Designed backend APIs for booking, guest, and operational management
• Implemented authentication and role-based authorization
• Structured the backend using Clean Architecture principles
• Handled validation, error handling, and API consistency

Architecture & Design Decisions

I chose Clean Architecture to separate core business logic from infrastructure concerns. This allowed the system to remain testable, maintainable, and adaptable as requirements evolved.

• API Layer: Handles HTTP requests, validation, and routing
• Application Layer: Business rules and use-case logic
• Domain Layer: Core entities and rules
• Infrastructure: Database, authentication, and integrations

Security Considerations

• JWT-based authentication for stateless API access
• Role-based authorization for staff and admin operations
• Input validation to prevent invalid or malicious requests
• Centralized exception handling to avoid data leakage

Performance & Reliability

• Optimized database queries for booking and availability checks
• Stateless APIs enabling horizontal scalability
• Clear separation of read and write responsibilities

Future Improvements

• Add Redis caching for frequently accessed data
• Introduce background workers for booking confirmations
• Implement structured logging and monitoring
• Add rate limiting for public endpoints

This project reflects how I design backend systems that are secure, scalable, and ready for real-world operational use.
