I developed an Enterprise Hotel Reservation System using Java, Spring Boot, React, PostgreSQL, Redis, and JWT.

The project allows users to search rooms, check availability, make reservations, and manage bookings. It also includes an admin panel for managing rooms, bookings, maintenance, and basic revenue and occupancy details.

One of the main things I worked on was preventing overbooking when multiple users try to book the same room at the same time. I used Redis distributed locking to handle concurrent booking requests.

I also implemented temporary room holds, date-based room availability, JWT authentication, payment flow, and dynamic pricing.
