Artez Chapman Professional Headshot

Network Operations Professional | Cisco CCNA Certified

8 Years Network Operations | CompTIA A+ • Network+ • Security+ | Expanding into Cloud & Automation

Network and IT support professional with 8 years of production network operations experience at Charter Communications. Cisco CCNA certified with a CompTIA trifecta foundation. Continuing to deepen expertise across networking, cloud, scripting, and enterprise Linux.

About Me

Born and raised in Florida. A '90s kid from the dial-up days — when getting online meant kicking everyone off the phone. Those early struggles to get connected were my first lessons in networking.

I built the foundation at the Center for Advanced Technologies at Lakewood High School, then pursued an Associate of Science in Computer Programming at St. Petersburg College (1 course remaining, expected 2026). From 2017 to 2025, I delivered Tier 1/2 network and VoIP technical support at Charter Communications (Spectrum) — handling connectivity, DNS, DHCP, device provisioning, and escalation workflows across residential and business accounts.

artez@journey:~$ cat technology-timeline
HS: Center for Advanced Technologies → coding & hardware fundamentals
SPC: AS Computer Programming → logic & problem-solving
2017-2025: Charter Communications → 8 years network operations
2026: Cisco CCNA (200-301) → certified May 2026|

Technology never stops moving so neither do I. With the CCNA laying a networking backbone, I'm continuing to build depth across cloud, automation, and enterprise infrastructure as our world adopts new computing paradigms.

On AI: as Kelsey Hightower put it, "I'm not interested in what AI can do, I'm interested in what I can do with AI." That's the posture. I use modern AI tooling to accelerate learning, sharpen documentation, and prototype faster — the same way previous generations of IT pros adopted scripting and search. The fundamentals still matter; the tooling just makes the work faster.

Ready to bring 8 years of production network experience and a CCNA-backed foundation to a team building real infrastructure.

Technical Projects

🏠 Docker Homelab Infrastructure

💻 View Code

Built and operated a 5-service containerized stack on Ubuntu Server 24.04 LTS to learn Infrastructure as Code, container networking, and GitOps fundamentals. Project paused to focus on Cisco CCNA pursuit (passed May 2026); resuming with Kubernetes (K3s) and Prometheus next.

🚀 Services Deployed

  • Portainer — Container management UI
  • Homepage — Custom dashboard with system monitoring
  • Nginx Proxy Manager — Reverse proxy with SSL
  • Grafana — Monitoring dashboards and visualization
  • PostgreSQL 16 — Database for applications

🎯 Stack Details

  • Platform: Ubuntu Server 24.04 LTS
  • Resources: 8GB RAM, 4 CPU cores, 50GB storage

🚧 Actively Building — Cloud, Automation, and Enterprise Linux

Following the CCNA, I'm building hands-on depth in four areas that pair with production network experience. Each is real, in progress, and being practiced in lab environments — not just a line on a resume.

☁️ AWS Cloud

Solutions Architect Associate certification in progress. Building on prior AWS exposure from supporting Charter's Spectrum TV platform migration. CCNA networking foundation maps directly to VPCs, subnets, route tables, and security groups.

⚡ PowerShell

Authoring automation scripts for network diagnostics and Windows administration tasks. Extending the script-execution experience from Charter's Jenkins-based diagnostic workflows into authoring my own tooling.

🐍 Python

Network automation focus — practicing with Netmiko, Paramiko, and REST API interactions. Building on the CCNA programmability domain and prior SPC coursework in Computer Programming.

🐧 RHEL / Enterprise Linux

Expanding beyond Ubuntu into Red Hat Enterprise Linux via the free RHEL developer subscription. Practicing system administration, package management, and service configuration in lab environments.

🤖 AI-Assisted Workflow: Using modern AI tooling (Claude, GitHub Copilot) to accelerate study, sharpen documentation, and prototype faster. AI is part of the toolkit — not a substitute for understanding the stack.

🛡️ Security Dashboard Exploration

PowerShell-driven dashboard exploring threat detection concepts and SIEM visualization principles.

Exploration project that built understanding of security monitoring concepts and observability — the foundation that led to implementing Grafana dashboards in the Docker homelab.

⚡ Network Diagnostic Automation

PowerShell toolkit built from real-world ISP troubleshooting workflows developed over 8 years at Charter Communications.

DNS resolution testing, gateway connectivity verification, port scanning, and packet loss detection — built around the actual diagnostic patterns I used daily.
