I build scalable Java microservices and event-driven platforms for millions of connected devices.

I've built and scaled backend platforms at Allstate, GlobalLogic, Yash Technologies, and Cognizant, supporting customer billing, Verizon IoT, equipment monitoring, travel booking, and financial transaction systems.

At GlobalLogic, I built Java and Golang microservices for Verizon IoT ThingSpace, handling 10M+ connected devices through MQTT, Kafka, and AWS. I improved throughput by 3x, designed secure REST APIs and multi-database architectures, and built an LLM-based Agentic AI system for automated device health monitoring and anomaly detection.

I focus on reliable distributed systems: event-driven workflows, resilient APIs, database performance, production support, observability, and cloud-native deployments with Kubernetes and Docker.
