Vasiliy Ivanov

From operations to engineering.

Vasiliy spent years in the Airborne and Special Operations community before moving into technical infrastructure. The transition wasn't a pivot. It was the same discipline applied to a different domain: clarity under pressure, planning for failure, executing without shortcuts, the skills that mattered in operations are the skills that build resilient engineering systems.

He founded Five Nines Consulting in 2024 to bring that operational discipline to building technology products. The company is small on purpose, focused on shipping things that work and taking on engagements where careful engineering makes a measurable difference.

"The standards that kept us alive in the field translate directly to the engineering room. Plan for failure. Move with intention. Don't make promises you can't keep. That's what builds systems people can rely on, and companies that last."

What he's building today

Vasiliy leads engineering on PromptSentry, FNC's flagship product. PromptSentry is an AI security guardrail that protects AI applications from prompt injection, jailbreaks, PII leaks, and explicit content. It's used by educational platforms protecting kids and by enterprises protecting their workforce. Visit PromptSentry

Alongside the product work, he is designing the framework for a veteran training program: a structured way to bring more veterans into engineering careers through hands-on technical mentorship. The program is in active development, not yet running cohorts. The goal is to launch it with the same standard FNC applies to everything else it ships. Learn more
