About

I work at the intersection of cybersecurity and systems engineering. My focus is on building secure system architectures and making risk-informed technical decisions. I see security not as an additional layer, but as a core part of system design. From requirements definition to validation and operational phases, I aim to ensure that security is considered throughout the entire lifecycle. I have experience working with multidisciplinary teams and different stakeholders, helping align technical decisions with program goals and operational realities. I believe sustainable security comes from well-defined requirements, structured design decisions and clear risk ownership.
