I build evidence-first systems where:
- value moves on-chain
- data stays private, but remains verifiable
- simulations become real UX for protocols
Right now my obsession is verifiable digital twins: telemetry β attestations β proofs β on-chain commitments.
- Visiting Student at KAUST CyberSaR Lab (applied ZK, protocol security, threat modeling)
- Building at Paracausal Labs (protocol primitives β products)
- Researching VehiclePassport and Digital Product Passport systems for vehicles and circular economy
π₯ Agentropolis (ETHGlobal HackMoney 2026)
