A sea of data distilled into five distinct signals.
MadCoolHiFi
The marketing engine behind the best showrooms in HiFi.
A managed marketing stack purpose-built for specialty audio dealers: social, local search, reputation, and lead intelligence. Steered by operators who have sold flagship gear on actual showroom floors.
MadCoolStuff
The practitioner's guide to AI.
Independent coverage of the AI that practitioners actually ship: hardware, models, and robotics. Reviews, benchmarks, and buying guidance for the operators building real systems, not chasing leaderboards or waiting for keynotes.
MadCoolMoney
A real-time dashboard for traders and investors.
Live markets data, signal-level charts, and the numbers that matter: filtered, framed, and made decision-ready without the theater. Built for readers who want the answer and the receipts.
MadCoolSocial
Daily social posts that sound like you.
AI-drafted, voice-matched social posts for any business or individual: fact-grounded, approval-gated, and auto-published across 24+ platforms. Solo $49, Business $149, Multi-brand $299 to $499. Built for operators who can't afford to go silent but don't have time to write a daily post.
MadCool Games
Noise in. Signal out. Press start.
MadCool LLC's game studio. Small, playable-in-the-browser titles built by an automated asset pipeline with a human at the gate: NOISEFLOOR, a one-thumb block puzzle with a rising noise floor, and the Speaker Setup Simulator, a listening-room placement coach with a real acoustic score. No store, no unlocks, no account.
What I do
I build the backends and the storefronts and the glue in between. Product engineering that sounds like writing, writing that leaves room for the product.
Day-to-day it looks like TypeScript, Postgres, a lot of Stripe, and a distrust of heavy frameworks. Weekends it looks like mixing desks, custom DAC filters, and arguments about speaker placement.
If one of the brands above is the right door, open it. MadCoolSocial is the widest one: anyone with a business fits. If you want to work together on something else, the contact link below is live.
