I build production systems where public infrastructure, security, and data intersect — from library platforms used by staff daily to cryptographic tools exploring modern encryption, privacy, and post-quantum design.

My work is shaped by a commitment to stewardship, integrity, and service — building systems that are not only functional, but secure, auditable, and intentionally designed.

Recommended projects to explore my work:

1. 📖 Crypto Compare (repo) — Algorithm reference & chooser across 17 cryptographic categories. Start here to understand why before you experiment with how.

2. 🧪 Crypto Lab (repo) — The central index for Crypto Lab — 48 interactive browser-based cryptography demos. From deniable encryption and post-quantum algorithms to visual attacks and zero-knowledge proofs. Everything runs client-side. No accounts. Just the math.

   crypto-compare is the map. crypto-lab is the playground. Use them together.

3. 🔐 Meow Decoder (repo) — Secure optical air-gap file transfer via animated QR-code GIFs. AES-256-GCM + Argon2id + ML-KEM-1024 + fountain codes. Explicit threat model, fail-closed design.

4. ✝️ Scripture Journey (repo) — A Christ-centered PWA mapping 200+ Old Testament prophecies to their New Testament fulfillments.

5. 🤖 AI Conversation Platform (repo) — Multi-agent LLM orchestration with circuit breakers, observability, and 90%+ test coverage.

By day, I’m a systems analyst (IT Librarian) behind mission-critical systems a public library depends on — patron registration, access control, ILS integrations, and automated workflows that staff and patrons rely on because they simply work.

Outside of work, I build air-gapped cryptographic tools, multi-agent AI platforms, and Scripture apps that matter to me personally. Scripture Journey and Hide in Heart aren’t side projects — they’re the same discipline applied to something eternal.

The cryptography work isn’t separate from my library career — it underpins it. Patron data is sensitive by nature. I built Crypto Lab, Shadow Vault, Meow Decoder, and related projects to understand AEAD encryption, key derivation, deniable containers, and post-quantum primitives at the implementation level — not just call a library and assume correctness.

Every production system I ship reflects that discipline: AES-256-GCM encrypted uploads, HMAC-validated webhooks, fail-closed parsing, and explicit threat models. The demos exist to make that discipline visible.

I use AI as a development partner — accelerating iteration without compromising architecture or correctness.

My Christian faith is the throughline — shaping a focus on clarity, integrity, and building systems worth depending on.

A research tool for secure data transfer across air gaps using animated QR code frames. The phone acts only as an untrusted optical channel — all cryptographic operations stay on the secure endpoints. Built as a tribute to my Navy-veteran father.

Key Features

• AES-256-GCM with Argon2id key derivation
• ML-KEM-1024 post-quantum hybrid keys
• Fountain codes for reliable optical transmission
• Explicit, versioned byte-level protocol specification
• Fail-closed parsing with tamper detection

Status: Actively hardening — not yet externally audited. All cryptographic primitives are standard, publicly vetted algorithms. Security depends on correct implementation.
