━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PERRY'S RÉSUMÉ - DISTRIBUTED SYSTEMS & P2P PROTOCOLS Perry Kundert // `+1-780-970-8148' ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 2026-09-14 R&D engineer with 30+ years building distributed systems that treat divergence, loss and partition as the normal case rather than the exception. Architected and prototyped HoloFuel's agent-centric, partition-tolerant transaction engine in Rust at Holo Ltd.: each agent owns its own signed state chain, settlement is bilateral, and nothing waits on global consensus. Built and deployed the Reed-Solomon erasure-coded, multi-route SCADA transport that still carries control traffic for Enbridge's pipeline network, and consensus over lossy RF channels for clearGRID's telemetry. Authored widely used protocol and coding libraries (`cpppo', `ezpwd-reed-solomon'), and capability-style authorization systems (`localwebauthn', `crypto-licensing') that grant scoped rights by possession of a signed token instead of by central accounts and ACLs. Most recently designed and verified a complete cryptographic monetary protocol end-to-end, from mechanism design through zero-knowledge circuits: evidence of carrying a protocol from first principles to a documented, checkable specification. Comfortable reading specs, arguing about invariants, and debugging what the lab result missed.

[holofuel-model] [alberta-buck] R&D Consultant, /Dominion R&D Corp./ (Remote, 2009–Present) ─────────────────────────────────────────────────────────── /Protocol, authorization and communications R&D for industrial, energy and fintech clients; remote systems that run unattended for years. Guide teams through cryptographic and distributed systems architecture./ • Authorization without central accounts: • `localwebauthn': self-hosted WebAuthn/FIDO2 passkey relying party; credentials and authentication material never leave the operator's infrastructure. • `crypto-licensing': Ed25519-signed, offline-verifiable licenses with DNS-based public key distribution (DKIM model); possession of a signed token grants a scoped right to a specific resource, with no license server in the critical path. • Protocol and coding libraries in wide use: • `cpppo': Python EtherNet/IP and CIP protocol implementation, deployed globally as the integration layer between analytics systems and PLCs. • `ezpwd-reed-solomon': high-throughput C++/JS/Python Reed-Solomon and BCH codecs, used by aerospace and defence developers for data on lossy channels. • `python-slip39': cross-platform Shamir secret sharing for seed backup and recovery. • Delivered rugged satellite-connected monitoring, communications and video systems across Alberta oilfields: intermittent, high-latency links, field-serviceable, diagnosable from 400 km away. • Designed and delivered a production generative-AI service with three interchangeable inference backends and copy-on-write session cloning, chosen deliberately for vendor reversibility and data sovereignty. • Mitigated a critical security flaw in a globally deployed enterprise collaboration suite. • Designed the *Alberta Buck* protocol, a complete wealth-backed monetary system, as a worked example of carrying a protocol from mechanism design to a checkable specification: • Identity-aware transfers gated on Chaum-Pedersen re-encryption proofs; unlinkable Pointcheval-Sanders credentials; privacy-preserving bearer notes over Poseidon Merkle commitment pools with Groth16 spend circuits. • Composed and sanity-checked the full cryptographic stack with executable `py_ecc' tests on BN254; proved completeness, special soundness and honest-verifier zero-knowledge of the bilateral disclosure proofs (independent formal review remains to be done). • PID-controlled issuance with median-aggregated independent controllers for oracle manipulation resistance; multi-year economic simulations in Python. • [Architecture] · [Formal Proofs] · [Identity System] · [Implementation] • Actively share research code and papers; author technical articles on Holochain, consensus, signal recovery and industrial communications.

Sr. IT Advisor, /Enbridge Pipelines/ (Edmonton, AB 2002–2009) ────────────────────────────────────────────────────────────── /Designed and deployed a cryptographically secured, Reed-Solomon erasure-coded, multi-route communications protocol for real-time pipeline SCADA; still in operation today./ • Architected the transport to keep control traffic flowing through crippling communications failures: erasure coding across independent routes rather than retry on a single path. • Implemented multi-path routing maintaining cryptographic integrity across hostile networks. • Developed solid-state RTUs for 24/7 control; <1 defect per 10K LOC in mission-critical firmware protecting $100B+ infrastructure. • Deployed hundreds of ruggedized units across critical infrastructure sites.
