A signal, not a CV. Drag the mark to scrub it.
Brands — 03
A sea of data distilled into three 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 info hub for AI hardware.
Independent coverage of the GPUs, accelerators, workstations, and edge devices actually building the AI economy — reviews, benchmarks, and buying guidance for the people running the models, not just reading about them.
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.
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. If you want to work together on something else, the contact link below is live.
