DoorDash
Merchant telemetry, experimentation platform, and live-cluster pipelines
Five years embedded in DoorDash's merchant and consumer pods. Led telemetry overhaul, built the experimentation council, and owned core ETL pipelines in Snowflake/Databricks/Airflow.
Problem
Merchant telemetry was fragmented and untrusted. A/B testing lacked a consistent framework, and segmentation pipelines couldn't handle real-time clustering needs.
Approach
Overhauled merchant telemetry schemas and ingestion. Co-built the experimentation platform and drove the measurement QA process. Designed segmentation and live-cluster pipelines. Owned the Segment source-of-truth.
Outcome
Telemetry trusted cross-org. Experimentation council launched. Live-cluster pipelines shipped. Dashboards in Sigma/Tableau/Mode rolled out to merchant and ops teams.
