Telematics Engineering student at UPM. I bridge low-level network infrastructure and high-level web software — freelancing with Astro and Tailwind, self-hosting everything on a Proxmox rig.

about

~/about.md
  • Studying Telematics Engineering at UPM — networks, protocols and the systems built on top of them
  • Freelance web developer — two client sites shipped with Astro and Tailwind
  • Homelab operator — Proxmox and Docker on a Ryzen 5 3600, VLANs on UniFi, Grafana watching it all
  • Security student — preparing for OSCP on HTB Academy, Parrot OS as the daily driver

Curiosity first: break it on purpose, then put it back better.

NOC-inspired personal site

The page you are looking at. Astro with two React islands, Tailwind v4, self-hosted fonts and zero tracking. Designed as a network operations center dashboard — because that is the world the work lives in.

Self-hosted services on a segmented network

A Proxmox host (Ryzen 5 3600 · GTX 1660 Ti · 16 GB) running Docker: Pi-Hole for DNS, a media stack, Tailscale for remote access. Grafana + Prometheus watch every container and node, on a network split into three VLANs.
