I removed the friction no one had measured.
Customers could buy a car wash at the pump without signing up. Online, they had to enroll first. That gap was invisible in the data until I went looking for it. I scoped a low-risk pilot, designed the guest flow in Figma, built the Next.js prototype, and shipped in a month. Monthly sales climbed 50%, and the pattern is now informing the broader e-commerce model.
