Tamper-Proof Records. Fraud Prevention. Private Blockchain.
Your sysadmin shouldn't be able to edit your audit logs. Your database should prove it hasn't been tampered with. I build the infrastructure that makes this possible — private blockchain systems that give you immutable records, cryptographic verification, and complete data sovereignty.
No tokens. No crypto speculation. Just bulletproof record-keeping for companies that can't afford data integrity failures.
What I Build
Tamper-Proof Audit Trails
Every record cryptographically sealed and independently verifiable. No admin can silently edit history.
Wire Fraud Prevention
Multi-party verification of wire transfer instructions on-chain before funds move. Real estate's $446M problem, solved.
Encrypted Document Vaults
Client-side encryption with blockchain content hash commitments. The server never sees your plaintext.
Private Chain Infrastructure
4-node BFT consensus, full history indexing, PostgreSQL read cache — production-grade from day one.
