Deployed tothe problem.

CS new-grad building deployed systems for defense, real-time comms, and AI infrastructure.

SCROLL

A defense contractor. A DoD program. A paying client. Three different fronts before my degree. All shipped, all still running.

Proof, in public

I build systems that keep working after I leave.

Deployments

Where someone hired or sponsored me to ship it: a defense contractor, a DoD-sponsored program, and a paying client.
