TravelNest - Hotel Booking Backend System Development

TravelNest is a backend system for a hotel booking platform, designed to handle room availability, bookings, and user roles in a clean and scalable way. It simulates the core backend of a real-world travel or hospitality SaaS application.

To build a reliable and maintainable backend that manages hotel listings, room availability, and booking lifecycles while exposing a clean API that can integrate easily with any frontend or mobile application.

Hotel booking systems often break down due to:

Poor handling of booking and cancellation flows

Room availability conflicts and double bookings

Weak separation between booking logic and persistence

APIs that become difficult to extend for features like reviews, pricing rules, or promotions

The goal was to design a system that stays simple but behaves like a production-ready booking backend.

I implemented a layered backend architecture with clear separation between domain logic, services, and API contracts.

Key outcomes include:

Robust booking lifecycle management (pending, confirmed, cancelled)

Availability validation to prevent double bookings

Role-aware behavior for guests and administrators

DTO-based API contracts for clean frontend integration

Extensible structure for future features such as payments, reviews, or notifications

TravelNest demonstrates my ability to design backend systems that model real world business workflows such as date based availability and booking state transitions while keeping the codebase clean, extensible and production oriented.
