I built cryptographic systems that solve a specific problem: organizations in aerospace, defense, and legal need to prove records are authentic and haven't been tampered with—and they need to verify this offline, without relying on networks or databases. I help teams implement sealed evidence systems that work exactly like that.

Most people think data security means having better databases or more encryption layers. That's backwards. I approach this differently: the seal itself becomes portable, verifiable by anyone, anywhere, with proof built directly into the packet. That's what changes how organizations handle evidence and compliance.
