Message

At Amazon, I implemented Python FastAPI inventory-query services and Java Spring Boot fulfillment-status endpoints for operational workflows. I improved API response time by a reported 35% through Redis caching and SQL query tuning.

I also built Apache Kafka consumers for asynchronous order-state events and automated application builds and release checks with GitHub Actions and Docker. I added CloudWatch logs, alarms, and dashboards to support production troubleshooting.

At The Walt Disney Company, I developed React interfaces and multi-step reservation forms, and integrated GraphQL queries into personalized content modules. Targeted component and API integration tests achieved reported coverage above 95%, while the GraphQL integrations improved API efficiency by a reported 30%.
