• Created five distinct Microservices in SpringBoot for managing Product, Inventory, and Security of the system.
• Implemented Service discovery pattern for services to locate each other on a network using Eureka server.
• Implemented a Circuit Breaker mechanism to improve system reliability.
• Used Kafka for asynchronous communication between microservices.
• Incorporated JWT for secure authentication and authorization.
• Employed both MongoDB and SQL databases. .
• Ensured observability and debugging ease by integrating Zipkin for Distributed tracing.
• Implemented an API gateway as the single entry point to the system, handling routing and security
