BookMyMeet | Spring Boot Backend Project with Kafka, Redis, MySQL & Google Calendar | Full Tutorial
BookMyMeet – Real-World Spring Boot Backend Project
In this video, I demonstrate my BookMyMeet backend project — a meeting scheduling and booking system built using Spring Boot and modern backend technologies.
The project focuses on solving real-world backend engineering challenges such as concurrency, distributed locking, idempotency, caching, asynchronous event processing, and third-party API integration.
🔧 Tech Stack:
• Java
• Spring Boot
• Spring Security + JWT
• MySQL
• JPA / Hibernate
• Redis
• Apache Kafka
• Docker
• Google Calendar API
• Google Meet
• OAuth 2.0
• Swagger / OpenAPI
🔥 Key Backend Features:
• User authentication and authorization
• Meeting/slot availability management
• Concurrent booking prevention
• Redis distributed locking
• Idempotency-Key based duplicate request prevention
• Redis slot caching
• Double-booking prevention
• Transactional booking workflow
• Outbox Pattern
• Apache Kafka event-driven architecture
• Asynchronous email notifications
• Google Calendar integration
• Automatic Google Meet link generation
• Calendar invitation and update notifications
• Booking cancellation and rescheduling
• Global exception handling
• Health monitoring for application dependencies

The main goal of this project is to demonstrate how concepts commonly discussed in backend/system design can actually be implemented in a real application.
📌 Important Backend Concepts Demonstrated:
• Concurrency Control
• Distributed Locking
• Idempotency
• Caching
• Event-Driven Architecture
• Outbox Pattern
• Transaction Management
• Asynchronous Processing
• OAuth 2.0
• REST API Design
This project was built as a practical backend engineering project to understand how production-style systems handle reliability, consistency, scalability and asynchronous workflows.
