7+ years building networks, managing systems, and securing infrastructure across finance, healthcare, and enterprise — grounded in Zero Trust principles.
Building Networks.
Securing Systems.
New York-based IT Infrastructure Engineer with 7+ years across network operations, systems administration, and physical infrastructure. I've built and secured environments for Fortune 500 firms, healthcare systems, and enterprise hospitality.
I operate where technical execution meets security — terminating fiber in a telecom room, managing IAM for 10,000+ users, or scripting automation. Everything is Zero Trust-aligned.
Currently focused on the CCNA, sharpening the network engineering fundamentals that anchor my work.
