He tests his own work by trying to break it before anyone else gets the chance — exactly the instinct you want in someone building a tool people will trust with a several-thousand-dollar decision.

The problem they picked
A used-car listing is six photographs and a price. Everything that decides whether it is a good buy — the open recall, the failure that model is known for at ninety thousand miles, what the noise on the test drive will cost — sits somewhere the buyer does not know to look. The team's own framing was that you meet the car the way you meet an online date, except the surprises run into the thousands.
RevOS pulls federal recall and safety data onto the listing itself, maps symptoms to their likely causes and repair costs, and keeps each car's history in a garage that is still there long after the sale.
“Buying a vehicle online is kind of like online dating — you see a couple of pictures, but when you meet in person there's a couple of surprises. For used vehicles, these surprises can cost upwards of thousands of dollars.”

How it was built
API Integration
NHTSA vehicle data pulled into the health report, so recalls and safety ratings sit alongside the listing itself.
Data Modeling
A diagnostic reference they researched and built by hand, mapping each symptom to its likely causes, repair cost, and severity.
Front-End Development
A digital garage that keeps each car's history between visits, so the maintenance log is still there the next time you open it.
