Most marketers use AI to write faster. I use it to build an operating system: a library of production AI skills, diagnostic toolkits, and financial models that run real client work every week. Everything here is pulled from that system, sanitized, and shared.
| Repo | What it is |
|---|---|
| media-launch-playbook | The complete system I used to take a stealth media brand from zero to multi-platform launch: positioning, brand system, episode distribution, community activation, measurement |
| claude-marketing-skills | Production AI skills from my "AI employee org chart": weekly client sweeps, a rigor and critique layer, a five-advisor decision council, Meta creative and unit economics engines |
| google-ads-diagnostic-toolkit | 10 diagnostic skills covering the full Google Ads lifecycle: wasted spend, CPA spikes, Quality Score, impression share, bid strategy, budget reallocation, reporting |
| media-infrastructure-cost-model | A 6-year cost model for content company infrastructure: storage, transfer, media asset management, seats. Built for a real board decision |
| roas-scenario-forecaster | 30/60/90-day ROAS forecasting with three scenarios and diminishing returns curves. No naive linear extrapolation |
Every framework here follows the same philosophy: systematize the repeatable, so human judgment goes where it matters. The Monday sweep runs itself. The negative keyword audit runs itself. The forecast model runs itself. What I spend my time on is the strategy those systems surface.

Note: client work in these repos is anonymized and abstracted into reusable frameworks. The thinking is real; the identifying details are not.
