Role Overview & Company Profile

FYLD, Inc. • Cryptographic Data Integrity & Distributed Systems

Enterprise data witnessing and tamper-evident cryptographic audit trail platform using distributed state-anchoring protocols and Merkle trees.

Co-founded and engineered the foundational systems architecture, low-level cryptographic notarization pipelines, and kernel event listeners enabling verifiable enterprise audit trails and distributed ledger integrity proofs.

Key Architectural & Engineering Achievements

  • • Architected and scaled an enterprise Data Witnessing platform in Golang, gRPC, and LevelDB/PostgreSQL, providing provable, tamper-evident cryptographic audit trails for corporate clients.
  • • Engineered cryptographic state-anchoring protocols utilizing Bitcoin/UTXO architectures and Merkle trees to establish immutable mathematical proofs of state on distributed networks.
  • • Optimized cryptographic hashing throughput by implementing low-level SIMD vector instructions (Assembly/Go), accelerating SHA-256 computation across high-volume data streams.
  • • Pioneered kernel-level file mutation observability by intercepting Linux kernel inodes (inotify), triggering real-time cryptographic notarizations with zero user-space polling overhead.
  • • Directed engineering best practices, CI/CD automation, and zero-trust cryptographic key management lifecycles across distributed microservices.
