Full-Stack Developer — LINE Mini App & Smart Farming Platform

We're building FarmLink, a LINE-native smart farming platform for Thai farmers. The app lets farmers manage their fields, receive AI-powered satellite alerts, and scout crops offline — all through LINE. The codebase is already scaffolded. We need a developer to take it to production. Tech stack you must know: NestJS (TypeScript) — two backend services already structured Next.js 14 / React — LIFF mini app (runs inside LINE) Supabase + PostgreSQL + PostGIS — geospatial farm data LINE Messaging API — webhooks, Flex Messages, LIFF SDK MapLibre GL JS — interactive farm maps with polygon drawing PWA / Service Workers / IndexedDB (Dexie.js) — offline-first mobile app AWS S3 — photo uploads via presigned URLs Nice to have: Python / FastAPI (AI engine for NDVI satellite analysis) Sentinel Hub API or Google Earth Engine Experience building for low-end Android / rural connectivity You should be comfortable with: Monorepo structure (npm workspaces + Turborepo) Thai language UI (or willingness to work with Thai copy) Mobile-first UX for non-technical users
