Flight Reservation System

A full-stack academic project that simulates an airline reservation engine. It empowers users to search for flights, reserve seats in real time, and manage itineraries with live availability updates.

Highlights

• Built a modular microservices architecture with Spring Boot, enabling independent deployment of search, booking, and payment contexts.
• Implemented WebSocket channels so reservation updates propagate instantly across dashboards without full page reloads.
• Containerised the stack with Docker Compose to guarantee consistent developer onboarding and reproducible environments.
• Hardened data integrity using MySQL transactions and optimistic locking for concurrent seat selection.

Outcomes

• Reduced booking conflicts to near-zero by combining WebSockets with robust locking and validation.
• Delivered comprehensive documentation, diagrams, and CI workflows to support future cohorts reusing the project.
