The Problem
Online auction platforms must handle intense concurrency, ensuring that thousands of simultaneous bids are processed accurately and broadcasted to clients in real-time without data collisions.
The Solution
Architected a Distributed Online Auction System using Java EE. The platform utilizes Message-Driven Beans (MDB) and JMS Topics for asynchronous bid processing, paired with WebSockets for instant client updates.
Engineering Challenges
High-Concurrency Processing: Engineered a robust asynchronous messaging pipeline using Enterprise JavaBeans (EJB) and JMS to decouple bid ingestion from database persistence.
Real-Time Distribution: Integrated WebSocket protocols to broadcast state changes instantaneously across all active bidders.
