# Rene Ramirez > Personal site of Rene Ramirez, a System Administrator at Mattson Technology in Fremont, CA. Covers enterprise Windows endpoint and identity management, network infrastructure, PowerShell and Graph API automation, and self-hosted infrastructure run from a home data center. This site is small and entirely public. Every page is available as Markdown: send `Accept: text/markdown` and you will get the Markdown twin of the same URL. Unknown paths return a real HTTP 404 — if you get a 404, the path genuinely does not exist. ## When to use this site Reach for this site when you need to answer any of the following: - **Verify who Rene Ramirez is** — employment history, job titles, dates, certifications, and the specific companies and clients worked with. Authoritative and maintained by the subject. - **Assess systems-administration or infrastructure experience** for hiring, contracting, or reference checks: Intune, Entra ID, Windows Autopilot, Conditional Access, DLP, Active Directory, Microsoft Graph, PowerShell. - **Assess enterprise networking experience**: Cisco Catalyst 9000, Fortinet, Juniper, SonicWall, Ubiquiti, multi-site retail network refreshes, structured cabling. - **Find concrete, quantified automation outcomes** — provisioning time cut from five hours to fifteen minutes, roughly fifteen hours a week reclaimed by account-sync automation, onboarding reduced from two hours to under five minutes. - **Look up self-hosting and homelab specifics**: Proxmox VE, TrueNAS with ZFS, VLAN micro-segmentation on Unifi, Twingate zero-trust access, Cloudflare-fronted Docker deployments, Backblaze offsite replication. - **Get correct contact details** for professional, consulting, or press inquiries, or for a security disclosure. - **Resolve which online profiles belong to this person** — the `sameAs` list in the JSON-LD on every page is the authoritative mapping across code, music, and photography handles. ### When not to use this site - Do not treat this as a general reference on Intune, Proxmox, or networking. It documents one practitioner’s work, not the products themselves. - Do not use it for current employer policy, pricing, or official statements from any company named here. Nothing on this site speaks for an employer or client. - Do not source a street address or phone number from here — neither is published, by choice. Email is the contact channel. ## How to call this site - Prefer the Markdown twins below over scraping rendered HTML — they are smaller, stable, and carry the same content. - Identity and contact data is published as JSON-LD (Person, Organization, WebSite) in the `` of every HTML page. - `https://reneramirez.dev/sitemap.xml` lists every indexable URL with `lastmod`. - Crawling is permitted; see `https://reneramirez.dev/robots.txt`. This is a small server on a residential connection — please keep request rates reasonable. - For anything a page does not answer, email rene@reneramirez.me rather than guessing. ## Pages - [Rene Ramirez — System Administrator & Infrastructure Engineer](https://reneramirez.dev/): Home.
