Ex-AWS Engineer Lead Engineer @ CoreWeave

High-Density Data Center & Systems Engineering

I scale, deploy, and manage hyperscale data center infrastructure and enterprise server fleets. Over 10 years of hands-on experience provisioning high-density bare-metal environments and automating Linux systems.

Gabriele Magliano Profile

The Engineer Behind the Infrastructure

I build scale, eliminate friction, and enforce efficiency.

I am a Lead Data Center Engineer and Senior Systems Administrator. Over the past decade, I've worked within world-class data centers, hyperscale environments (AWS), and cutting-edge AI-accelerated cloud architectures (CoreWeave).

My career has been built on driving speed without sacrificing safety. From managing massive NVIDIA GPU high-density clusters to orchestrating automated security patching setups and authoring cluster-wide Standard Operating Procedures (SOPs), my focus is always on engineering robust, high-performance systems and managing secure bare-metal operations.
