Guest Housing Booking Management System
A full-stack web application developed to digitize and streamline the guest house booking process at the University of Barishal. The platform replaces manual booking registers and phone-based reservations with a centralized system that provides real-time room availability, online reservations, and role-based management.

Overview
The University of Barishal operates guest houses in Dhaka and Barishal for faculty members, staff, and official visitors. Previously, the booking workflow relied on manual registers and administrative coordination, which often caused double bookings, lost records, and difficulty tracking room availability.
This system introduces a modern web platform where users can search available beds, submit booking requests, and track reservations, while administrators can manage bookings and monitor occupancy through a centralized dashboard.
Key Features
Real-Time Room Dashboard
Visual grid showing occupancy status of each bed with color-coded indicators across both guest houses.
Smart Booking Flow
Users can:
Admin Booking Management
Admins can create bookings on behalf of guests using live user search and autocomplete. All actions are recorded with audit notes for transparency.
Role-Based Access Control
Data Filtering & Export
Administrators can filter bookings by date, search users, sort results, and export booking data to Excel for reporting.
Technology Stack
Frontend: Next.js (App Router), TypeScript, Tailwind CSS, React Hook Form
Backend: Laravel REST API with JWT authentication
State Management: Zustand
Database: MySQL / PostgreSQL
API Communication: Axios
Data Export: SheetJS (XLSX)
Impact
The system replaces a fully manual booking workflow with a 100% digital solution, eliminating booking conflicts and providing real-time visibility into guest house occupancy for administrators.
