Product engineer and technical lead based in the New York metropolitan area.
I turn ambiguous, workflow-heavy problems into secure systems that people can actually operate, from product discovery through production.
I currently serve as Volunteer CTO at TROA, setting technical direction across software, UI/UX, network engineering, and IT operations.
