Network engineer, Chicago

DUSTIN
ALLEMAN

A decade of enterprise networking. I design it, run it, automate it, and build the tools and labs that prove it out.

How I work

Design it, run it, automate it, then explain it.

Ten years across help desk, network admin, enterprise support, and cloud-managed infrastructure. Routing, switching, and wireless at the packet level; containers, APIs, and automation on top. The last five years I have been the technical lead on Fortune 500 and federal agency networks, which means the job was never just the config: it was the root cause, the executive readout, and the runbook that kept it from happening twice.

Everything on allemanit.com is the proof: the homelab, the agents, the products, the labs.

The road here

Marine Corps to enterprise networks to whatever the lab is breaking this week.

  1. 2013-2017
    U.S. Marine Corps, where it started

    Cyber and network specialist. Learned to make mission-critical networks just work, under pressure.

  2. 2019
    CCNA and first network gig

    Earned my CCNA at Mesa CC and moved into enterprise network admin at OneNeck across Cisco, Juniper, and Palo Alto.

  3. 2021
    Enterprise cloud networking

    Moved into cloud-managed networking at scale: routing, switching, and wireless for enterprise customers.

  4. 2022
    High Touch and started teaching

    White-glove Fortune 500 support, and I started teaching CCNA at City Colleges of Chicago. Instantly hooked on the teaching.

  5. 2023
    Federal networks

    Technical lead for U.S. federal agency customers on a FedRAMP-authorized cloud platform. Compliance requirements on one side, mission uptime on the other.

  6. 2024-2025
    Build everything

    A homelab that runs like production, AI agents, automation. If I could break it and learn it, I did.

  7. 2026
    What's next

    CCNP in progress, degree wrapping in November, and looking for the seat where design, automation, and customer-facing work all count.

About

I'm Dustin. I've spent over a decade in IT: support, help desk, networking, engineering, infrastructure. It started long before the paycheck. I was the kid taking computers apart, breaking things and figuring out how to fix them. That curiosity turned into the career.

I did IT in the Marine Corps, carried it through a few companies after that, and these days I work on cloud-managed enterprise networking in a FedRAMP environment. I came up on the hands-on side: packet captures, escalations, enterprise gear. The goal was always to design and own networks, not just support them, and to build the tools I wished I had along the way.

So I build. Dashboards, AI agents, automation, a homelab that grew from scavenged gear into something that runs like production. A lot of it exists because I wanted the tool and nobody had made it yet, and because proving a thing out and explaining it clearly turns out to be most of the job. I also teach CCNA-level networking at colleges around Chicago, which is some of the most rewarding work I do.

Off the clock: Chicago lakefront skates, biking, anything outdoors, a Jeep with a permanent project list, and whatever the lab breaks that week.
