cat about.md

I'm an IT professional with 5+ years spanning enterprise endpoint management, network infrastructure, and cybersecurity operations. My background runs from desktop support and device management at ExxonMobil and BART all the way through federal infrastructure and security analysis supporting the DOE Special Technologies Laboratory. I'm CompTIA Security+ certified (SY0-701) and currently working toward VMware VCP-DCV.

Where I differentiate: I don't just keep the lights on — I monitor and harden the environment. I run a home lab with Wazuh, Suricata, and Kali Linux for active detection engineering, and I build tooling (TrenchWatch, this site) to stay sharp outside of the day job. I'm based in Dallas, TX, targeting cybersecurity analyst, systems administrator, and IT infrastructure roles, and I'm open to relocation.
