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

A Romania-based software engineer operating from a 44 m² apartment near Iași reports running a fully self-hosted AI and knowledge lab on a single Dell Precision Tower 7910 with dual Xeon E5-2699 v4 processors (88 threads), 503 GiB of ECC RAM and an AMD Radeon AI PRO R9700, with no cloud dependency. The setup includes a searchable library of 72,304 works, a local AI agent (lsn-agent-v3) that works through roughly 550 tools and 445 MCP tools with 894 tests, and a threat-intelligence platform holding 817 dossiers fed by home honeypots and intrusion detection. The builder presents the system as proof that teams can own rather than rent their AI and data platforms, with all figures read from the machine and refreshed every 30 minutes.

I build private AI and knowledge systems you own. 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. 72,304 works, searchable 445 MCP tools 817 threat dossiers 100% self-hosted What I can do for you Systems that belong to you , not a vendor 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. 🤖 https://www.shuffle-on.com/workshop.html Private AI on your own hardware 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.

I build things: infrastructure, furniture, music, sentences. If it's broken, I fix it; if it doesn't exist, I make it. - Sovereign AI & security lab A self-hosted library, a local AI agent and a live threat platform — on one machine, no cloud. - Professional software engineering A decade building and running production software and data platforms. - Builder & writer Carpentry, music and nearly 200 published essays in Romanian and English. More about the person and the machine I also write https://lsn.sonatural.life 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. Also known as: Cristian Lișneanu · Cristian Lisneanu · Dumitru-Cristian Lișneanu. Have a project? Let's build something that's yours . 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.
