Shopping list
Pantry + shopping PWA, in-browser SQLite + Neon sync
Shopping list is a PWA for groceries: pantry inventory, a pending list (with PDF) and an Urgent tab. Offline-first with SQLite in WebAssembly; online mode syncs through Neon Auth + Data API. Full case-study docs live as markdown in this portfolio.

The problem
Lists live in notes, chats or paper: quantities disappear, urgent items mix with the rest, and there is no printable PDF by aisle. Grocery apps demand an account on first tap.
The solution
Installable PWA with three tabs and an add-product modal (qty, unit, category). Real persistence in SQLite (sql.js + IndexedDB). Opt-in sync with Neon Auth and Data API; same-origin Netlify proxy so iOS/PWA keep the session. Capacitor 5 for Android.
