Message

At Cognizant Technology Solutions, I worked on KIOSK (Verizon) device data processing, implementing Spring Boot solutions, Java gRPC communication, and Protobuf contracts. I also integrated Apache Kafka to process device data and persist validated data.

For Macy’s, I developed Spring Boot microservices and REST APIs for an e-commerce platform, including Kafka-based event processing and Redis caching. I also developed AWS Lambda functions and wrote tests with JUnit and Mockito.

Earlier, I developed Spring Boot services and REST APIs for insurance, healthcare, and education applications, and built responsive ReactJS interfaces for FIITJEE Ltd. My experience also includes banking and insurance applications using COBOL, JCL, VSAM, and DB2.
