CardGauge
CardGauge started as a question — could a single person build a credible, end-to-end product for trading card collectors? The answer turned out to be yes, and the result is in production: an AI-powered card scanner that identifies cards from a phone photo, real sold-price comps from completed sales, a transparent grading decision tool, a hot/cold market tracker, a Pokémon-specific section, and a Cards-vs-Wall-Street feature that compares card returns to real stocks.
The app runs at app.cardgauge.com on Render with a Supabase database and accounts, backed by a custom Node/Express API wired to OpenAI Vision, eBay, sold-sales data and Stripe payments. The marketing site sits on Wix. Every feature is real and working — no fake data, no placeholder dashboards, no "coming soon" pages disguised as products.
This is the proof that we can build complex, multi-feature, real-data products solo and keep them running. If we can do that, your small-business site is straightforward.
