Architect of the VAChEC Sovereign Standard
A globally recognised trade economist and professor, Joseph is the inventor of the VAChEC system and core Sijobri intellectual property.
He oversees the scientific integrity of the Sovereign Standard, establishing the protocol that bridges the gap between international trade law and digital settlement.
His research defines the mathematical foundations required to address the ongoing crises in international trade, including 2026 changes in EU customs rules, with deterministic certainty.
Lead Technical Engineer for VAChEC Implementation
Nathaniel brings enterprise-grade technical discipline, honed through a distinguished background at IBM, to the Sijobri technical layer.
He is the lead architect of the secure gateway connecting physical imports to the VAChEC cryptographic compliance ledgers.
His work ensures that the Sijobri engine is not only high-performance but remains institutionally secure and compliant with the highest standards of European data residency.
The Sijobri Mission Statement
"Sijobri Ops AG’s mission is to architect the neutral digital infrastructure for global trade, without ever transacting within it.
Strict Neutrality: We are a pure utility provider. We do not compete with our logistics partners, nor do we trade against our platform clients.
Data Sovereignty: We do not sell, mine, or monetise client data. Our federated architecture ensures that national data remains within its jurisdiction, strictly adhering to GDPR and data residency mandates.
Immutable Integrity: Every transaction processed through the Sijobri Sovereign Bridge is anchored in physical reality, validated by our deterministic compliance engine."
