## About

```text
I am a dedicated Data Engineer with extensive experience in building scalable data solutions and optimizing data processes. Currently, I serve as a Lead Data Engineer at Airbnb, where I have successfully achieved sub-10-minute latency for data serving and ingestion by developing a multi-region data lake on AWS. My commitment to enhancing platform reliability has led me to standardize deployment processes using GitLab CI and Terraform, ensuring high availability and integrity of data assets.

Previously, I worked at Tecton and Instacart, where I implemented test-driven development practices that significantly reduced issue tickets and improved data quality checks in ETL pipelines. My efforts in designing a recommendation system at Instacart generated an additional $5 million in revenue, showcasing my ability to leverage data for business growth. I am passionate about fostering collaboration between data engineering and data science teams to drive innovative solutions and enhance user engagement.
