Featured Project: CardLedger

A full-stack portfolio manager that treats Pokémon cards like financial assets. I built CardLedger to give collectors deep insights into their collection's value while maintaining the speed of a local tool. It solves the "database bottleneck" by prefetching compressed data, allowing users to search 20,000 cards instantly without network latency.

• Investment Analytics: Visualizes portfolio performance over time, comparing your actual cost basis against daily market value updates.
• Zero-Latency Search: Custom Zustand & IndexedDB engine updates results instantly on every keystroke—no pagination required.
• Optimistic UI: Collection management feels native app-fast, updating the interface immediately while syncing with the database in the background.
