The Challenge
What made it hard.
Card pricing comes from noisy, inconsistent marketplaces. Collectors expect stock-app precision on data that arrives messy.
Our Approach
How we built it.
We built a normalisation and pricing pipeline across sources, cached time-series for instant chart ranges, and a scanning flow for adding cards without manual entry.
