The Engineer
Behind the Stack

Network engineer. Automation builder. Perpetual tinkerer.

I'm a Network Engineer III with deep roots in enterprise infrastructure — datacenter switching, perimeter security, cloud connectivity, and the automation that brings it all under control.

My day job lives in the intersection of Cisco Nexus fabrics, Palo Alto NGFWs, and AWS hybrid architectures. After hours, I'm running a homelab (concrete876), building MCP servers, and automating everything that sits still long enough.

Originally from Jamaica. Currently building in Clayton, NC. Coffee optional. BGP required.
