Wavy Club · Surfboard rental platform

Challenge

WavyClub is №02 in my series of experiments building real products with AI in the loop. The point was never to ship a side project — it was to develop a build process I trust as design, specification, and engineering collapse into one loop. I gave myself two days and used an existing surf rental product, SurfsUp, as a fixed reference. A known target removes the blank-page problem and turns every decision into one about interpretation, structure, and taste — which is where the learning lives. I know SurfsUp from the inside as a partner through my FinFun channel, so I could see the small gaps that only reveal themselves once you've lived with a product long enough to stop noticing them...
