Projects

Hotel Booking System (Airbnb Clone)

April 24, 2026 – Present

Developed a scalable backend using Spring Boot with layered architecture to manage hotels, rooms, bookings, and users through RESTful APIs. Implemented hotel search with filters (location, date, availability) and complete booking workflow including room allocation and status management. Integrated Spring Security with JWT-based authentication and role-based access control for Admin, Manager, and Guest operations. Designed relational schemas using MySQL and improved performance with Redis caching for search and availability queries. Used Apache Kafka for asynchronous booking events and containerized the application using Docker for scalable deployment. Ensured data consistency using ACID-compliant transactions for booking and payment workflows, preventing partial failures. Implemented centralized error handling, input validation, and logging for improved reliability, maintainability, and debugging during production operations.

Parcel Management System

April 24, 2026 – Present

Designed and developed a scalable backend using Node.js and Express.js to handle parcel creation, assignment, and approval workflows with efficient API structures and modular routing. Implemented a flexible settings module allowing admins to dynamically add or modify parcel handling rules and departments without code changes, ensuring adaptability to business evolution. Integrated JWT authentication and middleware-based authorization to distinguish between Admin and Employee roles, ensuring data integrity and restricted access to sensitive operations. Utilized MongoDB with Mongoose schemas for efficient data storage, validation, and relationships between parcels, users, and departments. Optimized queries and indexes for high performance.
