Message

At Amazon, I designed a data ingestion service and REST API-driven pipeline to collect and process App Store and Google Play reviews. I also built a serverless workflow with AWS Lambda and S3 that reduced manual data extraction effort by 95%.

I integrated AWS Translate and Comprehend to normalize and categorize multilingual reviews, and Amazon QuickSight to support analytics and dashboards. I also integrated Bazaar marketplace ID with a notification service for configurable in-app notifications.

At Infosys, I developed Java and Spring Boot backend features and REST APIs within a microservices architecture, using PostgreSQL and Kafka for event-driven updates. Earlier, I developed WireHub, a React application with real-time stock data, and built an Audible application clone with Java, Spring Boot, Angular, and MySQL.
