"I build AI tools that change how teams work — replacing slow, engineer-dependent processes with self-service systems anyone on the team can run."
//about

Some background on me.

I'm the marketing-technology and AI developer at YouVersion (the Bible App, 1 billion+ installs). When we started wondering what AI could actually do for our marketing, I didn't wait for a mandate — I just started building, ran up a real token bill exploring what was possible, and shipped two production systems on my own. One picks the best message for each user with bandit ML algorithms (Next.js + TypeScript); the other lets non-technical marketers launch localized campaigns across 70+ languages. The work contributed to a 20% increase in daily active users and a 200% increase in monthly revenue. I'm now the tech lead on a half-dozen web apps for our organization.

//01

NNexus

An agentic personalization engine that autonomously chooses what, when, and how to message each of 50M+ users in real time. The ML is built from scratch in TypeScript — Thompson Sampling, LinUCB, and HDBSCAN persona clustering — with a reward loop that learns from live engagement.

//02

BBeacon

A self-service AI platform that lets non-technical marketers design, configure, and launch cross-channel campaigns themselves — work that used to require an engineer. Built on a 24-component creative schema and a 17-handler workflow registry with a governed Draft → Approved → Sent flow.

VVerseCut

Turns a single reference into a polished image or video ad — composited, captioned, and voiced entirely in the browser. Rendering runs client-side via FFmpeg compiled to WebAssembly with on-device text-to-speech, keeping cost and infrastructure near zero.

WWayfinder

Generates deep links and QR codes that route people to the right content across platforms — built so marketing and growth teams can spin up, manage, and track campaign links from a single, fast interface.

CCaptured

A build dashboard and ingestion pipeline for capturing and structuring sites — a wizard-driven flow that scrapes, parses, and tracks builds end-to-end, with a clean operator view over the whole process.

The best system I'm part of.

Eight years married to Maggie, dad to four. The systems I care about most don't run in production — they're at home. Same principles, though: show up every day, build for the long run, and sweat the details no one else sees.

Let's build something.

I'm exploring staff / senior engineering roles where I can own meaningful surface area and turn ambiguous problems into dependable, shipped systems. The fastest way to reach me is email.
