Network Engineer · CCNA · Monticello, MN

Nathan Treadway

I spent 15 years leading operations teams at FedEx Ground. Now I design, build, secure, and automate networks. I earned my CCNA in August 2026, and I run a working multi-site Cisco and UniFi lab where everything on this page is built, broken, fixed, and documented.

What I'm looking for

An entry-level network role: network technician, NOC, network administrator, or wireless/ISP field technician, within about 30 miles of Monticello, MN (St. Cloud, Buffalo, Maple Grove, and the NW metro) or remote.

What I bring

Hands-on Cisco and UniFi skills, plus years of running shifts, leading people, hitting service deadlines, and solving problems under pressure. I document everything I build.

My path

  1. 2011–2020 · FedEx Ground, South Bend, IN

    Pickup & Delivery Manager

    Led delivery operations: daily route planning, staffing, safety, and on-time service. I learned to troubleshoot fast when a system or plan breaks mid-shift.

  2. 2020–2026 · FedEx Ground, Maple Grove, MN

    Sort Manager

    Ran a high-volume package sort, which is a real-time flow system much like a network. That meant throughput, bottlenecks, people, equipment, and process discipline. It's what pulled me toward how networks move traffic.

  3. 2026

    NetworkChuck Academy CCNA (May–Aug)

    Monday–Friday daily check-ins with Jeremy Cioara (CCIE), Zach Hill and Chuck Keith (NetworkChuck). 2–3 hours a day of subnetting, VLANs, STP, OSPF, ACLs, NAT, wireless, and security fundamentals.

  4. Aug 28, 2026

    Passed the Cisco CCNA

    Started a 90-day plan: five portfolio projects, targeted applications, and interview prep.

  5. Sep 2026

    Designs, published labs, and automation

    Designed a dual-stack two-site hospital network, published a multi-site troubleshooting lab (11k+ impressions), and started network automation with Ansible.

  6. Oct 2026

    Built and secured the physical lab

    Racked a two-zone Cisco lab (OSPF campus and eBGP branch), connected it to my UniFi network, built a Raspberry Pi console server, and ran a security review of the production firewall.

    Physical build-out, automation, and this site

    Bringing up every console and device in the lab, working through the Ansible phases, and documenting it all here every week.

Projects

Each project lists the problem, what I built, and the tools I used.

Published

Multi-site troubleshooting lab

Problem: Find and fix faults across an HQ, branch, and data center network.

Built: A three-site topology with deliberately injected routing, switching, and ACL faults, and a step-by-step write-up of how I isolated each one.

Two-site hospital network design

Problem: A network for a 200-employee hospital: a main campus with 140 staff and a remote campus with 60.

Built: A dual-stack IPv4/IPv6 design with four VLANs per site (Clinical, Admin, Support, Management), OSPF single area, HSRP at the core, DHCP, NAT, edge ACLs, SSH-only management, a /30 WAN link, and loopback addressing.

Building

Two-zone enterprise lab on real hardware

Problem: Practice campus and branch networking on real Cisco gear, not just in a simulator.

Built: A Lab1 campus zone on OSPF and a Lab2 branch zone on eBGP. VRRP gateways across the 3750 and both 2811s. 3560 PoE access switches with BPDU Guard, DHCP snooping, and DAI. An optional L3 EtherChannel. I validated the design first in an FRRouting simulation, then wrote 14 setup and test documents (95 pages).

Building

Lab ↔ production integration

Problem: Connect a lab to a live home network without either side breaking the other.

Built: A trunk from a UniFi switch, route exchange with the UDM Pro over OSPF and BGP, ACLs that limit the lab to the internet and the Proxmox host, and SSH-only management from one dedicated station.

Complete

Firewall security review & hardening plan

Problem: Could any device on my network be pulled into a DDoS botnet?

Built: A read-only audit of the UDM Pro: port forwards, UPnP, IPS, and VLANs. I found the gaps (flat IoT network, unfiltered outbound traffic, no inter-VLAN segmentation, partial IPS coverage) and wrote a six-step hardening build sheet: an IoT VLAN, IPS on all networks, anti-spoofing, segmentation, outbound IoT filtering, and rollback steps.

Building

Out-of-band console server

Problem: Reach every device's console without moving cables around.

Built: A Raspberry Pi with a 7-port USB hub and stable udev device names. It also runs ser2net for network console access, plus TFTP for config backups and rsyslog for central logging. I debugged silent consoles down to individual cables and USB-serial chipsets.

Building

Wireless: Cisco WLC and UniFi Wi-Fi 6/7

Problem: Full coverage across two floors, plus enterprise controller practice.

Built: A UniFi U6 Pro and U7 Pro deployment on each level. In the lab, a Cisco 5508 WLC runs lightweight 3502 APs, and one AP is converted to autonomous IOS.

Now

Network automation with Ansible

Problem: Stop configuring every device by hand.

Built: A seven-phase plan based on Automate Your Network by John Capobianco, updated to current Ansible. The phases cover toolchain setup, reconnaissance, tactical changes, data models and Jinja2 templates, documentation generated from data, drift detection, and CI with GitHub Actions. I use Ansible Vault from day one and libssh to reach older IOS SSH.

Planned

Hybrid cloud and capstone design

Problem: Extend an on-prem network into AWS, then design a greenfield network end to end.

Where I'm headed

My roadmap. If you're starting the same path, feel free to follow it.

  1. Finish the Ansible phases on the physical lab and publish the repo.
  2. Python for networking: Netmiko, then Nornir, then NAPALM, then pyATS.
  3. NetBox as a source of truth, and NETCONF/RESTCONF through Cisco DevNet sandboxes.
  4. CCNA Automation (200-901) as my next certification.
  5. Cloud networking: AWS VPC with Terraform, and containerlab for multi-vendor practice.
