MoodHaven Journal
A cross-platform journal app with a built-in health tracker, built in Rust and Tauri. Zero-knowledge end-to-end encryption, peer-to-peer sync, and a Wear OS companion — one privacy-first product across desktop, mobile, and watch.

I'm Ken — a decade keeping systems running, now shipping privacy-first software with AI as my pair. I built MoodHaven (an end-to-end-encrypted journal in Rust + Tauri), submit CVE detection modules to Metasploit, and write about what I learn. I'd rather build the thing and earn the understanding than wait until I'm "expert enough."

Selected work
A cross-platform journal app with a built-in health tracker, built in Rust and Tauri. Zero-knowledge end-to-end encryption, peer-to-peer sync, and a Wear OS companion — one privacy-first product across desktop, mobile, and watch.
Auxiliary scanner modules authored and submitted to the Metasploit Framework (Rapid7) for recent CVEs — Audiobookshelf (CVE-2025-25205), a Next.js middleware bypass (CVE-2025-29927), and a LiteLLM pre-auth SQL injection (CVE-2026-42208). Lab-verified, benign detection only.
In their words
Demonstrated a love of learning and the level of commitment necessary to succeed.
Corren McCoy Professor, Regent University Highly motivated, professional, and dedicated worker.
Earl Duff Manager, U.S. Navy There wasn't a task too big or small that he couldn't successfully tackle; he is a great team player.

A small RAG-style assistant that answers questions about me, built with no vector database, no framework, and a model bill measured in cents — here's the whole architecture, and the guardrails that keep a public endpoint from spending my money.
ReadDoes AI make us dumber, or sharper? The honest, fact-checked version — what the research really says about AI and your brain, its real environmental cost, the quiet ways it flatters you, and how to use it well.
ReadA browser remake of the 1979 Atari Lunar Lander that turned into real orbital physics, historic Apollo missions, and an AI Theater where you watch a neural net learn to land in real time. Built with AI, for fun.
ReadWork with me
Open to IT, infrastructure, and AI-focused roles — remote or Boise. I'm happiest where IT, infrastructure, and AI overlap — keeping systems healthy and using AI to do more with a lean team. Hiring, building something privacy-minded, or want to compare notes? I read every message.
