Improving reliability in financial systems. Building with AI on the side.

About

I'm a Systems Engineer at Goldman Sachs focused on improving the reliability of post-execution derivatives systems — root cause analysis, incident management, and building AI tools to make that work faster. My background spans data engineering, machine learning, and full-stack development across fintech, edtech, and media startups. I hold an MS in Business Analytics from UC Davis and a BS in Computer Science from University at Buffalo.
