Smart Fridge

A household inventory project that keeps food visible, prioritizes use-soon items, and reduces avoidable waste through better daily decision support.

Live demo coming soon

Case Study Summary

  • Problem: Families lose track of inventory and expiry windows in shared fridges.
  • Audience: Shared households trying to reduce food waste and duplicate purchases.
  • Role: Solo engineer across frontend and API integration.
  • Scope: Inventory entry, status tracking, and use-soon prioritization.
  • Timeline: App repo created 2024-11-11; backend repo created 2025-05-05; both maintained through 2026.
  • Stack: React Native, TypeScript, Node.js API.
  • Release surfaces: Mobile app architecture with a separate backend service for content and inventory state.
  • Constraints: Fast item input on mobile and low-friction daily maintenance.
  • Technical decisions: Typed item states and expiry fields to support predictable filtering and reminders.
  • Results: 2-repository architecture (app + API), explicit lifecycle states for active/use-soon/expired items, and an implementation timeline spanning 2024-2026.
  • Public metrics note: User/download counts are not published; this page reports only verifiable implementation scope.
