About Me

I'm an IT and security engineer based in San Diego. By day I run identity, endpoints, SIEM, and compliance. The rest of the time I build software.

On the IT side that means Microsoft 365, Intune, Entra ID, Sentinel XDR, and a mix of Azure and AWS. On the code side I work in TypeScript, Node.js, and PowerShell, shipping on Azure Functions and Cloudflare Workers.

Right now I'm building Rallypoint, an offline-first festival-planning app on Cloudflare Workers, D1, and Durable Objects.
