Case Study: Cross-Platform Travel Booking Mobile Application

Role: Full Stack Developer Frontend Repository: GitHub - Mobile App (Frontend) Backend Repository: GitHub - Backend API

Overview

I built this Travel Booking Mobile Application as a personal project to improve my skills in React Native, Node.js, and PostgreSQL. The goal was to create a cross-platform app where users could explore destinations, book trips, and manage their travel history all from a clean, responsive interface.
The design was based on a Figma prototype that I translated into a real-world product using React Native with Expo for mobile and Node.js for the backend API.

Project Goals

Build a full-stack mobile app with a real-time booking experience.
Implement smooth navigation and data synchronization between frontend and backend.
Deploy the backend properly.
Design a beautiful, Figma-inspired interface that feels modern and responsive.

How I Built It

Frontend (React Native + Expo)
I used React Native to make the app work seamlessly across Android and iOS.
Implemented Expo navigation for user-friendly routing and smooth transitions.
Used Context API for global state management and session persistence.
Integrated REST APIs to fetch destinations, trip details, and booking history.
Followed the Figma design system closely to maintain UI/UX consistency.
Backend (Node.js + PostgreSQL)
The backend was built using Node.js with Express, connected to a PostgreSQL database.
Developed secure REST APIs with JWT-based authentication.
Used query optimization and indexing to improve response times.
Designed relational models for users, destinations, and bookings.
Implemented error handling and validation for API robustness.

Key Features

Browse and book travel destinations.
View trip history and manage bookings.
Receive real-time updates and push notifications.
Secure login and session management.
Smooth and clean UI built from Figma designs.

Results

Through this project, I gained deeper experience in:
Building production-ready mobile apps with React Native and Expo.
Designing RESTful APIs and optimizing them for performance.
Implementing secure authentication and handling data consistency across devices.
The final app runs efficiently on both Android and iOS, offering users a seamless experience from browsing destinations to managing their travel plans.
