Principal Engineer in Telecom, Applied Cryptographer

justin@thefrozenfire.com | frozenfire.eth

Currently

Doing applied zero knowledge application development, currently focused on client-side-friendly ZK proofs for on-chain KYC/AML. My research focus is in how one builds user-facing zero knowledge protocols which use simple cryptographic primitives, have minimal verification costs, clear trust assumptions, and which are relatively simple to audit. I am particularly focused on creating ZK protocols which interoperate with real world concerns such as legal reputation, regulatory compliance, and real world identity.

  • Telecom systems engineering (SMS, VOIP, SMPP, SIP)
  • Security engineering (Cryptography, threat mitigation, compliance)
  • Network engineering (Cloud provisioning, K8S clustering)
  • Operational intelligence, data science
