Day job
Atlantic Packaging
Business Application Developer, AI & Integration · since mid-2026

Straight out of my master's, I joined Atlantic Packaging's development team. I work on AI tools and on the integrations that connect the company's business systems, so data and work move between them without anyone copying it by hand.

Four months in, it's where I'm learning what production software actually takes: real users, real data, and systems that can't go down.

The VaR engine that put five models on trial

Five Value-at-Risk models forecast out-of-sample every trading day for ten years on a stock/bond/gold portfolio, then judged with the same backtests banks use to validate their own risk engines.

1.19%exception rate for Extreme Value Theory, the only model to pass Kupiec. The Normal-based models breached 2.5× too often.

About
I learn by building.

I'm a recent grad with a master's in Computer Science & Information Systems from UNC Wilmington, now a developer at Atlantic Packaging.

The thing I keep coming back to is the tech side of finance: quant research, systematic trading, and the models underneath them. When something catches my interest, whether that's markets, tennis, space weather or an AI pipeline, I build it and check it against real data.
