India

Message

At Notion, I reduced CSV import processing time by 50% through asynchronous operations and the removal of unnecessary API calls. I also made imports non-blocking and validated the improvement with production dashboards.

I led the development and production launch of Notion’s Salesforce Integration, from Beta to General Availability for Enterprise customers. I also built monitoring dashboards and developed retry, checkpointing, and error-handling systems to improve reliability.

Before Notion, I built data pipelines at Microsoft, including ingesting a DNS dataset into Delta Lake with Spark. At GitHub, I built Slack and Teams integrations, and my projects include a containerized Spark runtime on AKS with Prometheus and Grafana observability.
