## About

```text
At iRhythm Technologies, I led the migration to a modern lakehouse with Fivetran, Apache Iceberg, Snowflake, and dbt, retiring a legacy Redshift warehouse and reducing data platform infrastructure costs by 40%.

I built iRhythm's enterprise data lake and later managed its data systems engineering team of 13. As Staff Data Services Architect, I provision platform infrastructure with Terraform and built an AI-powered search and discovery platform over the data lake using Glean.

Earlier, I managed database and DBA teams at Zuora and Rackspace, and worked across MySQL, Postgres, and cloud infrastructure. I also speak, read, and write Spanish fluently.
