## About

```text
At Airbnb, I redesigned the Homes + Experiences + Services Data Platform as the company moved beyond a Homes-only warehouse. I kept existing Homes marts correct through the 2025 launch and established modeling and key standards so data from different product lines could be joined consistently.

I also extended Airbnb’s Metrics Platform onto new product grains. From 2021 to 2024, I owned metric storage and querying, with versioned definitions materialized into queryable datasets so analytics, reporting, and experimentation shared one definition.

At Verisk, I worked on Liability Navigator (LNAV), owning batch pipelines that turned carrier claim data into comparable-claim and injury-serving tables. I joined medical extraction to claim and payment history and added data-quality checks and backfills to support reliable liability and settlement decisions.
