IT professional based in Los Angeles with experience across enterprise infrastructure and application support. Currently working as an IT Application & Support Analyst at Chrome Hearts, supporting business users and enterprise systems in a luxury retail environment.

Background spans network administration (Cisco Meraki, Ubiquiti), endpoint management via Apple MDM and CrowdStrike Falcon, application support, and cross-platform systems work across Windows and macOS.

Whether it's diagnosing a production issue, deploying a network, or writing SOPs that actually get used — I care about clean execution and systems that work without drama.
