# A sovereign AI lab on one machine in my apartment – zero cloud > Source: > Published: 2026-10-24 17:06:44+00:00 # 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. See the agent → [📚](https://www.shuffle-on.com/knowledge.html) ### A messy archive, made searchable & provable Turn decades of scattered files into a catalogue you can search by meaning, ask questions of, and verify file-by-file. See the library → [🛡️](https://www.shuffle-on.com/live-feed.html) ### Security monitoring & threat intelligence Honeypots, intrusion detection and a forensic pipeline that turns raw attacks into attributed, sourced intelligence. See it live → [☸️](https://www.shuffle-on.com/intelligence-platform.html) ### Kubernetes & platform engineering A whole production stack on one node — SSO, observability, backups, networking — automated and documented. See the platform → Proof, live ## Not a pitch deck — a running system These numbers are read from the machine itself, not typed by hand. Refreshes from the live system every 30 minutes. Featured work ## Three flagships, *built from scratch* [📚 Knowledge](https://www.shuffle-on.com/knowledge.html) ### A library that reads, answers and proves every page 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. Explore the library → [🤖 lsn-agent-v3](https://www.shuffle-on.com/workshop.html) ### An AI engineer that checks itself Proposes a plan, waits for your yes, works through ~550 tools, and flags its own unsupported claims. 894 tests. Meet the agent → [📡 Live Feed](https://www.shuffle-on.com/live-feed.html) ### Every attack becomes intelligence A home honeypot and web sensors, enriched and linked into a graph of relationships and published dossiers. Watch it live → [🛡️ Defense](https://www.shuffle-on.com/defense.html) ### Four layers, by hand Router, community IDS and app auth as one system — bans learned here are shared back to a global community. See the defense story → [🔐 The Access Engine](https://www.shuffle-on.com/the-access-engine.html) ### Access control that understands the cluster A from-scratch SSO platform: a visual access matrix, service auto-discovery and a GitOps audit trail. Read the deep-dive → The human behind it ## 44 square metres. *Infinite output.* 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. - **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.
