Jaskeerat Brar

Systems Engineer @ Goldman Sachs

Reliability and incident response for trade processing systems. On the side, I experiment with AI to build helper tools and prototype data-heavy projects.

About

I work on reliability of large-scale financial production systems and use AI as a personal force multiplier to build internal-style tools and data-heavy side projects. My background spans fintech, edtech, and media. I hold an MS in Business Analytics from UC Davis and a BS in Computer Science from University at Buffalo.
