A signal, not a CV. Drag the mark to scrub it.
Brands — 04
A sea of data distilled into four 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 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 $299–499. Built for operators who can't afford to go silent but don't have time to write a daily post.
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 door, anyone-with-a-business friendly. If you want to work together on something else, the contact link below is live.
