Software Engineer @ Blue Origin · Physicist · Builder

Went from simulating dark matter at CERN to shipping the software that runs avionics test campaigns and HPC workloads at Blue Origin.

View My Work Get In Touch

Dark matter to launch hardware.

Hey y'all - I'm Jacob.

Physics degree from Florida Tech. Dark matter at CERN. Quantum chemistry and spectroscopy on HPC clusters at ENSCO. Now building avionics verification and HPC platforms at Blue Origin.

The common thread: computation has to be correct when the stakes are real.

I've also spent years running organizations - student government, LGBTQ+ groups, fraternity boards. People problems are harder than software problems.

Work with me

Available for consulting.

Two practices, beyond the day job - pick the one that fits.

Science & Engineering

Research code that ships.

Slow simulations, legacy code, HPC that won't scale.

LGBTQ+ & Lifestyle

Tech built for your world.

Web, apps & community platforms, built from the inside.

If it has to work the first time,
I want to work on it.

Especially interested in aerospace, hard science, and anything with real constraints.
