The approachBuild the platform. Improve the foundations.

What I do

I'm the founder of Query.Farm. I build tools that connect databases to the systems around them, and contribute upstream to DuckDB, Apache Arrow, and Apache Iceberg. My work spans query execution, data interchange, and running custom code through SQL.

Previously, I led data platform engineering at Schonfeld, built cloud infrastructure at Two Sigma, and co-founded businesses in commerce and live video. I work across the code, the architecture, and the team that ships it.
