AI Systems & Agentic Security · Independent designer & builder
I design and build secure multi-agent AI systems as a solo operator — orchestrating AI tools rather than writing code by hand. My focus is keeping human control over autonomous agents that hold economic authority. Proven, not theorized: three sequential proofs of concept, each verifiable on a public blockchain.
Flagship project
NEXUS-ART
An experimental art marketplace where autonomous AI curator-agents with distinct, locked personalities evaluate and bid on tokenized artworks. Every action that moves money requires an out-of-band human confirmation, backed by an independent hardware veto. Built solo; smart contract verified on Sourcify (Base Sepolia testnet). It grew from one question — how could AI fund human artists rather than replace them.
Autonomous single-agent curation — POC-001
A curator agent scores works against a fixed rubric on its own, with no human in the scoring loop.
33 / 33 acceptance criteria passed · settled on-chainLive two-agent bidding duel — POC-002
Two agents with distinct, locked personalities compete for a work in a real proxy war, each stopping at its own ceiling.
10 real bids · 0 invalid · settled on-chain · payout split exact to the weiHardware-enforced settlement — POC-003
The winning fund-moving transaction is signed on a Ledger device that computes and displays the transaction's own hash independently of the host — the host never holds the key.
hardware veto · host-independent verificationCapabilities
- Agentic system design — multi-agent, locked personalities, evaluation logic
- Human-in-the-loop & custody security — out-of-band confirmation, hardware veto, two-key separation
- AI orchestration — designing, building, and shipping systems end-to-end by directing AI tools
- Security doctrine & specification — threat modeling, written specs, reproducible verification
- On-chain deployment & verification — contract deployment, Sourcify, testnet operations
How I work
I don't hand-write code. I design the system, then orchestrate AI to build, audit, and ship it.
SSH, hardware-wallet operations, and on-chain verification stay under my direct control. A single person can now stand up and secure a working multi-agent economic system. That is the point — not a caveat.
