A Valencia CTO’s notebook on hospital software, homelab infrastructure, IoT security, and coding agents in regulated healthcare.

Landing page captured for the 2026-09-12 issue.

Field notes

The site links three strands of work that are rarely presented together: a home lab built with Proxmox VE 9 and Vault, offensive study of BLE and Zigbee devices, and coding-agent adoption inside a regulated medical product. Its interactive CV runs in the browser using TF-IDF, question classification, and conversation memory rather than an LLM or server. The author also documents a career spanning hospital RTLS, six scientific publications, two books, and two granted patents.
