Message

At VMware by Broadcom Software India Pvt. Ltd., I built REST APIs and backend services for NSX Manager and owned NSX-T Edge upgrade orchestration. I designed resumable, idempotent upgrade steps that recover from mid-step failures across 640+ Edge VMs.

I was technical lead for NSX-T Edge clustering and high availability across multiple releases, and designed Policy APIs that became the standard configuration interface for Edge services. I also redesigned Edge redeployment to verify failover readiness and replace an Edge through a health-checked cutover.

Earlier, at NeoAccel India Pvt. Ltd., I developed enterprise SSL VPN products, including gateway and management components for authentication, access control, and configuration. I’m now building hands-on experience with Spring Boot microservices, Kafka event-driven systems, and Java 21 virtual threads.
