I build web products end to end.Lately, the AI that runs inside them too.
Eight years shipping websites and apps for agencies, startups, and my own company. These days most of my work is getting AI agents to do real jobs in production, and building the products around them.
- 8+
- years shipping production web software
- 185
- game characters with AI-made art and voice
- 3,175+
- ad creatives from one generative pipeline
- $1.5M
- first-month revenue from a tool I built at NAIC

Post2Site
Turns a small business's Instagram into a real website that keeps itself updated.
A business signs up, an AI build agent researches them, scaffolds a site, customizes it, and deploys it. A scheduled job keeps pulling new posts in and Gemini turns them into menu items, events, and catalog entries. Nobody on my side touches the site by hand.

Rumble of Ages
An idle gacha RPG with 185 gods and legends. Every portrait, animation frame, and voice line comes out of a pipeline I built.
From-scratch turn-based battle engine with a deep effects system and 170+ automated tests, cloud saves on Supabase, offline play, and a Canvas visual-effects engine. The content side is a multi-model generation pipeline with checks that catch model drift before anything ships to players.

TrueCommission
Commission and incentive-pay software a real sales team runs on every day.
Laravel and React across the full stack, from schema to UI. Payroll and commission logic where a wrong number costs somebody money, so I verify what a field actually means against real data before touching a calculation.

Astro · Consulting · AI integration
Agency years, in three sites
Built while at Jubilant Digital Marketing. WordPress, Craft, HubSpot.
Timberline Adventures
WordPress. Integrated an external booking platform with dynamic trip data and custom admin screens.
ArchWell Health
Craft CMS. IP-based provider geolocation, automated provider PDFs, faster location search, HubSpot workflows.
Red Six Media
WordPress. Custom theme rebuild for performance and SEO, bespoke plugins, pixel-accurate Figma build.
Claude Code, Codex, MCP, and a lot of briefs
Most days I direct agents more than I type code.
I use Claude Code and Codex the way a lead uses a team: I write the brief, set the guardrails, and review the work. The interesting part was never getting one good result out of a model. It's getting the hundredth one to be just as good, in production, without me watching.
Multi-agent
Post2Site build agent
A primary model that plans the work and dispatches subagents through research, scaffold, customize, and deploy. New site types ship as reusable skill modules without touching the orchestration.
MCP server
ClipMango
An agent-first content studio. The core is an MCP server, so any AI harness can drive the product as typed tools. The web UI and the agent interface are two thin adapters over one shared core.
Runs unattended
Scheduled agents
Daily research briefs, expert-knowledge curation, and narrated briefing videos rendered from HTML, all produced on a schedule and reviewed by a second agent that did not build them.
Gemini in production
Gemini integration for Game Plan AI
Tiered model routing by workload, Google Search grounding with citations, thinking-budget control, structured JSON output, and multimodal vision behind a health and training app.
Image generation
Generative ad production
Multi-panel comic ads with consistent characters across frames, tested at volume across two product lines. 3,175+ creatives and counting.
Cloned voice
This site
The narration you can turn on is my own cloned voice. The pipeline scripts live in the repo.

How I got here
I'm in Kansas City, Missouri. I got into this through LaunchCode back in 2016, then a couple of agencies where I learned to ship every day and keep a lot of client sites healthy at once.
The straw hat in the logo is a One Piece thing. Rumble of Ages started as a way to teach myself game engines and turned into the project where I learned the most about making AI dependable.
If you want the honest version of what I'm like to work with: I'd rather show you a working thing than a slide about it.
