Showcase builds
Working products built to be clicked, not described. Each one is live and needs no signup to look around.
A usage based billing product, both sides of it. A public pricing page and a four step checkout that creates a real account, and the admin console behind it that meters what customers consume, prices it against plan allowances, projects the invoice before the period closes, and records every change with the role that made it. Eleven screens, three roles you can switch live, and every blocked control explains why. Checkout is simulated and takes no payment.
Behind it, a real database. Cloudflare D1 holding 19,000 rows across 11 tables,
read through Pages Functions that aggregate in SQL rather than pulling rows into
the worker. Try /api/health on the demo.
