I'm on the security team at Werner Enterprises, where most of my time goes into SIEM/SOAR, Automation work, and Cloud Security. I write detections, build SOAR playbooks, and monitor cloud infrastructure

I studied cybersecurity at the University of Nebraska Omaha, with a concentration in cyber operations and cyber defense.

Work

Cybersecurity Analyst, Werner Enterprises

May 2026 – present

Full-time since May 2026. Started on the team as a Cybersecurity Analyst Intern, Aug 2025 – May 2026.

Google SecOps

  • Detections. I write YARA-L rules against UDM data. One example: I noticed a service account being renamed and reused in a way that didn't look right, traced the app_add and app_remove events back to the same UUIDs, and wrote rules to catch admins targeting their own accounts and unauthorized username changes.
  • Playbooks. I build SOAR playbooks that pull context and take action in other systems through their APIs and webhooks, so analysts don't have to do the same lookups by hand on every case.

Cloud Security Posture Management

  • I review cloud posture findings, figure out which ones actually matter, and work with the owners to get misconfigurations fixed.

Incident Response

  • I take part in incident response, from the first alert through investigating what happened, scoping what was affected, and containing it.

Day-to-day SOC work

  • Triage of user-reported phishing in PhishER, including pulling apart suspicious attachments.
  • Responding to DLP alerts.
  • Case handling in SecOps SOAR.

Python scripting

  • I write Python scripts that work with the Chronicle API, the gcloud API, the Cloudflare API, and others to automate tasks we'd otherwise do by hand.

Scrum Master Intern, Werner Enterprises

May 2025 – Aug 2025
  • Ran standups and other ceremonies for Salesforce, InfoSec, and Networking teams.
  • Helped plan the company's third PI Planning session of 2025.
  • Built a few AI-assisted workflows to cut down on repetitive team admin.

IT Intern, Pierre's TechHeads Inc (Offutt AFB)

2024 – 2025
  • Hardware and software troubleshooting and repair.
  • Set up small networks and built a few websites for clients.

Mobile Expert, T-Mobile

2021 – 2023
  • Device support and sales. Got recognized a few times for customer service.

Projects

Sentinel Llama

repo

An intrusion detection experiment that watches Windows Security logs (4625 failed logons, 4720 account creations) and has a local Llama 3.2 model, running through Ollama, label each event as clean or suspicious. Before the model sees an event, it pulls related MITRE ATT&CK entries from a Pinecone index so the verdict has some real context behind it.

Python, Ollama, Pinecone

Home malware lab

A Cuckoo3 sandbox on Ubuntu for detonating samples. Getting it to run meant nested virtualization (KVM/QEMU inside VMware Workstation Pro) and working around Windows host settings that kept getting in the way.

repo

One HTML file hosted on Azure Static Web Apps, deployed by GitHub Actions on every push. DNS and TLS go through Cloudflare.
