Lead Member of Technical Staff (LMTS) — HBase Public Cloud. Founding engineer of the team in India. Three promotions over seven years.

Public-cloud distributed-systems infrastructure for one of the largest NoSQL fleets at Salesforce. My work spans the HBase + Hadoop stack: CI/CD, release automation, fleet stability, cost / capacity, and the long-running architectural migrations that turn monolithic on-prem services into multi-tenant cloud-native ones on Kubernetes/AWS.

In 2020, head-down at work, I let my health slip. One morning a back injury left me with temporary lower-body paralysis. The doctor said my body was the cause. That was the day I changed how I lived. Four years and 42 kg later I finished Ironman 70.3 Goa.
