I am a Senior Network Architect with an architecture-first security focus: segmentation, control of lateral movements, and measurable risk reduction – not just buying more tools.

My particular strength is making security design understandable – both technically and in business language – so that decisions become comprehensible and sustainable.

Typical project size: 2 data centers / ~2,500 users / Hybrid Cloud.

Multi-vendor experience – vendor-neutral architecture approach.

Hands-on – implementation depth, not just slides.

I enjoy working with teams, transferring knowledge, and leaving environments measurably better than I found them.
