A sovereign AI lab on one machine in my apartment – zero cloud

10+ years building software professionally — and a whole sovereign lab on one machine in a 44 m² apartment in Romania: a self-hosted library, a local AI agent and a live threat-intelligence platform. Nothing leaves the hardware.

Plain terms: I design and run the kind of platforms teams usually rent by the month — except these run on hardware you control, and I understand every layer end to end.

A capable AI agent and model stack that never sends your data to anyone's cloud — it plans, uses your tools, and checks its own work.

Turn decades of scattered files into a catalogue you can search by meaning, ask questions of, and verify file-by-file.

Honeypots, intrusion detection and a forensic pipeline that turns raw attacks into attributed, sourced intelligence.

A whole production stack on one node — SSO, observability, backups, networking — automated and documented.

These numbers are read from the machine itself, not typed by hand.

Refreshes from the live system every 30 minutes.

72,304 works curated by meaning. Ask it questions, read in your language, and verify any file against a signed ledger anchored in Bitcoin — plus 400 offline reference books built into search.

Proposes a plan, waits for your yes, works through ~550 tools, and flags its own unsupported claims. 894 tests.

A home honeypot and web sensors, enriched and linked into a graph of relationships and published dossiers.

Router, community IDS and app auth as one system — bans learned here are shared back to a global community.

A from-scratch SSO platform: a visual access matrix, service auto-discovery and a GitOps audit trail.

A small apartment in a village near Iași — two kids, four cats, and a datacenter. I build things: infrastructure, furniture, music, sentences. If it's broken, I fix it; if it doesn't exist, I make it.

A self-hosted library, a local AI agent and a live threat platform — on one machine, no cloud.

A decade building and running production software and data platforms.

Carpentry, music and nearly 200 published essays in Romanian and English.

I also write poetry and philosophical essays — because infrastructure for the mind and infrastructure for machines aren't so different. Every mistake is a lesson; knowledge never dies.

Beyond the screen: harmonicas, guitars, handpan, saxophone, drums and an 800 W hi-fi so the music never ends; a full carpentry setup for wood and metal; and a disaster-ready household with its own food, water, heating and power.

The machine: a Dell Precision Tower 7910 — dual Xeon E5-2699 v4 (88 threads), 503 GiB ECC RAM, an AMD Radeon AI PRO R9700 GPU, NVMe arrays and a Synology NAS, a MikroTik CCR1009 router, a 14 kWh battery with generator and solar, running Ubuntu 24.04 and K3s. It serves 7 AI models locally and runs 67 Kubernetes namespaces.

Private AI, a searchable knowledge base, a security stack, an infrastructure you actually own — I build these from a village apartment. Imagine what I can build with real resources.
