IT Engineer focused on support, systems, automation, and secure software operations
Arizona-based technologist who works across user support, infrastructure, automation, and software. I like work where technical problems need to be diagnosed clearly, systems need to stay reliable, and improvements need to be documented so the next person can move faster.
- Operational troubleshooting: calm user support, clear ticket notes, root-cause thinking, escalation-ready documentation, and follow-through until the issue is actually resolved.
- Systems fundamentals: Windows, Linux, DNS, networking basics, SSH, Tailscale, Docker, VPS operations, Pi-hole, monitoring, and service health checks.
- Automation and tooling: Python, JavaScript, Bash, APIs, n8n workflows, and small utilities that turn repeated manual checks into repeatable processes.
- Software delivery: web projects, REST APIs, Git/GitHub workflows, deployment, accessibility-first UI, and maintainable code over flashy complexity.
- Security and reliability habits: verify before changing, protect credentials, document what changed, read logs carefully, and prefer simple systems that can be supported under pressure.
- Homelab operations: VPS, Tailnet, Pi-hole DNS, Docker-hosted services, monitoring, and private dashboards.
- Support-ready automation: scripts and workflows that reduce repeated manual checks and make system state easier to verify.
- Web and software projects: recruiter-facing portfolio, public deployments, responsive UI, APIs, and accessibility-focused implementation.
- Accessible technology: building and testing with screen-reader and low-vision usability in mind.
