About
“The best security architectures don't start with technology — they start with understanding the business.”
That's what I do as a Sales Engineer in the security industry: I sit at the intersection of deep technical knowledge and real business conversations with CISOs, CIOs, and IT leaders at enterprise manufacturing companies. I help organizations with up to 45,000 seats move from legacy network and security stacks to a cloud-native zero trust model — not just because it's more secure, but because it reduces complexity, cuts costs, and enables the agility their business demands. What got me into Sales Engineering was the combination of technology and people. What keeps me here is the impact — helping enterprises fundamentally rethink how they connect and protect their business.
How I work
Understand before you explain
Simple is harder than complex
Be honest, even when it's inconvenient
