I build the production LLM, voice, and security systems businesses run on. Co-founder of MYG Media in Vienna — voice agents answering real clinic and club phone lines, post-quantum tooling, and the automation behind them.

Most client work is private, so what is public here is the systems work: security, cryptography, and tools I wanted to exist.

Urfael · JavaScript · Electron · MCP · MIT A self-hosted, voice-capable AI assistant built blast-radius-first. The brain listens on a unix socket with zero TCP ports, untrusted turns run a no-egress read-only profile, and plugins load as data inside a --network none container, sha-pinned at consent.

It ships a security claim you can run instead of read:

npm run security   # boots the real daemon, attacks it, prints a pass/fail table
# → 11/11 real-world attack classes resisted · 128/128 checks passed

44,000 lines across 254 modules with zero runtime dependencies, under 1,400 passing tests.

Rustchain · Rust A blockchain from scratch with no framework: ed25519 signatures, proof-of-work consensus, Merkle trees, a wallet, and peer-to-peer networking. Signature verification binds the signing key to the sender's address, so a valid signature from an unrelated key is refused.

Forge · TypeScript · Electron Bulk media tooling — AI image and video upscaling, batch compression, audio conversion. GPU-accelerated, entirely local, no uploads or accounts. Shipped for macOS, Windows and Linux.

BrainVault · TypeScript · Tauri Local-first notes with markdown, wiki links, a force-directed graph view, and a browser extension. Your notes never leave your machine.

OpenBuild · TypeScript · Vue An open-source visual website builder: drag-and-drop canvas, reusable component system, one-click deploy.

Code Translator · Python Translates code between languages across several AI providers, with a VS Code extension.

StartupCouncilAI · TypeScript · Next.js A panel of AI advisors that debate a business question and return a synthesis, not one opinion.

GREMLIN · Python A voice AI that interrupts your coding session with absurd feature demands. Built for laughs, kept because it is genuinely funny.

TypeScript Python Rust Swift · React Next.js Vue Tailwind · Node FastAPI Electron Tauri · PostgreSQL Supabase SQLite · Docker Cloudflare AWS Railway

AI: LLM orchestration (Claude, GPT, Gemini, Mistral), MCP servers and clients, agentic systems, RAG, ElevenLabs conversational voice Security: post-quantum readiness (NIST FIPS 203/204/205, CNSA 2.0), adversarial red-teaming of agent systems, prompt-injection containment, sandbox and capability design
