Hey, I'm Christopher 👋

I'm an IT Service Desk Analyst II focused on automation, infrastructure, and operational reliability. I turn hands-on work into documented, evidence-backed projects that reduce manual effort, improve visibility, and make team workflows easier to follow and support. If it's repetitive, I automate it. If I can't verify it, I don't trust it.

What I'm working on right now

By day: building AI Ops tooling for a global service desk — n8n queue reporting, Jira automation, agent-assisted shift handoffs, and KBA lifecycle tooling. All governed, all git-backed, all designed to make manual work disappear. That work lives at CLorenzo_wkinect.

Outside of work: the labs below — infrastructure-as-code, home network engineering, and the cert path toward cloud/platform work.

Featured projects

Project What it is
Home Network Infrastructure / HA DNS Validated, high-availability DNS and failover: Pi-hole, Unbound, Keepalived, Gravity Sync, Prometheus/Grafana monitoring. Where a lot of the learning started.
Managed Network Infrastructure Lab Omada/ER605 managed cutover complete — subnetting, VLAN planning, firewall policy, rollback plan documented.
VPS Cloud Infrastructure Lab Linux VPS hardened with DNS/public routing in place; containerized app deployment, reverse proxy/HTTPS, monitoring, and backups planned.
AWS Network Automation Lab AWS networking as code — a reusable Terraform/OpenTofu VPC module, a Python drift-check CLI with tests, and CI. Learning project, not deployed infrastructure.

A full-stack network-ops dashboard and a governed homelab-ops system live in private repos. Happy to walk through them.

Technical stack

  • Infrastructure: Linux · Proxmox · Docker / Compose · Tailscale
  • Networking & DNS: Pi-hole · Unbound · Keepalived · Omada · ER605
  • Automation & validation: Python · Bash · PowerShell · pytest · GitHub Actions
  • Observability: Prometheus · Grafana · Alertmanager
  • Cloud & IaC: OpenTofu / Terraform · AWS networking-as-code
  • AI & Automation: n8n · Jira API · Copilot Studio (work context)

Certifications in progress

Cert Status
AWS AIF-C01 (AI Practitioner) 📖 Studying — target Sep 2026
HashiCorp Terraform Associate 📋 Planned — Oct 2026
AWS CLF-C02 📋 Planned — Nov 2026 (free attempt after AIF)
AWS SAA-C03 📋 Planned — Q1 2027

How I work

  • Learn the fundamentals, then build something real with them
  • Validate results through tests, CI, or operational evidence
  • Document what was proven — separate private operational detail from public-safe case studies
  • Use AI as an accelerator while independently reviewing and validating its outputs
