// critical systems by day · homelab by night
Hi, I'm Harry 👋
I keep life-critical 999 systems running - then come home and tinker with a rack full of blinking lights.
🧰 A bit about me
The short version.
By day I'm Head of Critical Systems for an NHS ambulance service - 999 call routing, computer-aided dispatch, telephony, all the stuff that has to already be working the second someone dials 999. Proudest moment: standing up a 400-plus-seat control room from an empty building to go-live.
By night I run Dabble Solutions, a Kent MSP, and build web tools for fun that got a bit out of hand - mostly the Take Home Network of public-sector pay calculators. Nearly everything I make is born on the homelab - Proxmox, UniFi, Home Assistant, a heap of local AI - then moves out to proper hosting once it's ready.

I'm building out the Take Home Network, poking at transport data, and open to director-level infrastructure & technology roles.
