United States

Message

At Dell Technologies, I built Angular modules for IT infrastructure portals that cut page load time by 20%, and designed Spring Boot microservices deployed on AWS. I also secured REST endpoints with JWT and Spring Security and improved vendor API reliability with retry and fallback logic.

Previously, I built React dashboards and Kafka pipelines at Hexaware Technologies, and developed Java healthcare services at CitiusTech using HL7 feeds and GCP. I also built an Intelligent PDF Query System with semantic search and a secure online banking application with real-time fraud monitoring.
