I build data systems, and I teach AI to use them.

I get paid to make data move fast and AI behave. Then I go home and do it again for free.

About
At work I build data systems and AI tools at Verisk. Pipelines, migrations, the company's data inventory, and an internal agent I rewrote the context for and built the evaluation against. I also run the review process every new data and AI request goes through.
On my own time I run VantaPool, an equity-swap analytics product in ClickHouse, and BallGPT, a March Madness model backtested across 18 tournaments.
The smaller tools are open and on GitHub. My day job and my side projects are the same hobby.
The method is usually the same: map the data, write down the edge cases, and check every result against something real.
