Message

At HP, I designed and developed Spring Boot microservices and RESTful APIs for cloud-native enterprise applications, using object-oriented design principles.

I worked with Spring Cloud, Eureka, API Gateway, OpenFeign, Redis, and Kafka to support distributed backend solutions and event-driven communication.

I improved system performance through caching strategies, database access optimization, and exception management, and used JUnit to support quality validation.

At Wipro and on the Apple account, I delivered Java backend modules and REST APIs, refined database operations, and contributed to enterprise workflows and integrations. I also developed an E-Commerce Order Processing Microservices Platform with User and Order services, Eureka, API Gateway, Feign Client, Kafka, and MySQL.
