Senior Infrastructure Architect
New Jersey · 20+ Years in Enterprise IT
I’ve spent my career solving complex problems in large-scale corporate environments. My focus has always been the same: lower downtime, reduce operational risk, and find the best tools and solutions to keep the business running efficiently.
Over two decades I’ve worked across industries, from financial services and pharmaceuticals to healthcare technology, professional services, and manufacturing. I’ve held roles ranging from system administrator to senior architect, building infrastructure at every scale along the way.
My deepest expertise is in virtualization and cloud platforms, but I work across the full stack – compute, storage, networking, automation, and security. I’ve led data center builds from the ground up, migrated thousands of workloads across platforms, designed hybrid cloud architectures, and built the automation frameworks that hold large environments together.
This blog is where I write about the real, practical side of infrastructure work. Expect honest takes on migrations, platform comparisons, and the day-to-day decisions that don’t make it into whitepapers.
