Offline-first mobile calorie tracker for African cuisine. React Native, NestJS, PostgreSQL, Docker, k3s. # African Calorie Tracker — Project Skeleton Monorepo for the calorie tracking app: a React Native (Expo) mobile app, a NestJS + PostgreSQL backend, and Docker/infra for running it all. Built to run **fully locally at zero cost** — you only pay for a server when you decide to launch to real users. ## Structure ``` backend/ NestJS API (TypeScript) src/ auth/ signup/login (email + phone), OTP, JWT, trial/entitlement users/ profiles, calorie-target calculation (the "engine") foods/ food database + search endpoints logs/ log entries, day records, weigh-ins sync/ offline sync endpoint (push/pull by updated_at) common/ shared utilities, guards migrations/ 001_init.sql LAUNCH 7. k3s migration (portfolio phase) ## Notes - The calorie engine math lives in BOTH mobile (offline) and backend (authoritative). See calorie-engine-spec.md. - Free core works offline forever. Trial/paywall enforced via on-device expiry date + anti-clock-rollback, confirmed on next online sync.
