Overview

Keto Kit is a comprehensive keto lifestyle app I built from the ground up — React Native mobile client plus a NestJS / Supabase backend. It ships AI-generated weekly meal plans, a recipe database with smart search, intermittent fasting tracking, food logging with barcode scanning, and a gamification engine that keeps users engaged day over day.
