Jeff Kirk Jr.

Background

I'm Jeff Kirk Jr. — most people call me Jay. I spent 11+ years in investment operations at institutional firms including Man Group and State Street, building expertise in fund accounting, trade operations, and financial data management across hedge funds, mutual funds, and ETFs.

Over time I noticed that the most valuable work — pattern recognition, cross-portfolio analysis, operational intelligence — was being done manually by expensive people running spreadsheets. So I started building AI systems to do it better, faster, and continuously.

This site is where those systems live. Everything here is production-grade, running against real data on real infrastructure — not demos.

Career Timeline

What I Build

Each project on this site is a production system I use personally, built with real data pipelines, real databases, and real infrastructure running on hardware I own.

The lab these pipelines run on

Everything here runs on hardware I own and maintain — not a managed cloud I rent by the hour.
