About

I'm a strategic infrastructure leader based in Torrance, California, currently serving as Supervisor of Systems Administration at Hypermedia Systems. I specialize in modernizing legacy environments into cloud-native, containerized infrastructure that scales.

My work spans the full infrastructure stack — from bare-metal Proxmox clusters and VMware virtualization to multi-cloud Terraform deployments, end-to-end observability with the LGTM stack, and zero-trust network security with Palo Alto and Cloudflare WAF.

I also integrate generative AI tooling (Claude Code, Gemini API) into SRE workflows to accelerate root-cause analysis and script development.
