Platform
A unified architecture for agricultural data
Five layers, 23 services, one shared data and event layer. Data from the assistant, sensors, drones and cameras converges automatically into a single season record.
System architecture
Every module goes through one API gateway and shares one data layer
Layer 1
Users & channels
- Farmer app
- Co-op & enterprise web
- Expert console
- QR trace portal
- Partner API
Layer 2
API gateway & identity
- Authentication
- Multi-tenant authorization
- Rate limiting
- Audit logs
Layer 3
Business & AI services
- Core platform
- AI layer
- IoT & drones
- Traceability
- Business
Layer 4
Shared data & events
- Kafka
- PostgreSQL · PostGIS · pgvector
- Time series
- S3 object storage
- Data lake
Layer 5
Edge & on-farm devices
- LoRaWAN sensors
- Edge gateway
- Pumps, valves
- Cameras
- Drones
Service catalog
23 services in 6 domains
Each service owns its data and talks over APIs and the shared event stream, so it can be built and sold independently.

AI layer
A controlled AI agent, not a Q&A bot
MLOps loop: every expert correction or farmer-confirmed outcome becomes new labeled data; models are evaluated per crop before release and can be rolled back.
Orchestrating language model
Leading LLMs via an LLM gateway with failover
Open models can be fine-tuned later to cut cost
Image diagnosis
YOLO / RT-DETR with EfficientNet, ViT
Fine-tuned on expert-labeled field data
Speech
Whisper fine-tuned for Vietnamese, natural TTS
Essential for older farmers
Forecasting
Gradient boosting, LSTM, Transformer
Per-plot outbreak risk, harvest timing
Drone & satellite imagery
Segmentation, NDVI, NDRE
Spots stressed plants before the eye can
IoT, drones & cameras
Edge first, cloud second
Sensors & auto irrigation
- Long-range LoRaWAN, long battery life, solar
- Edge gateway runs irrigation rules offline
- MQTT over TLS, per-device certificates
- Signed over-the-air firmware updates
Drone disease monitoring
- Multispectral and RGB cameras
- Orthomosaic stitching, NDVI
- AI maps disease hotspots to the app
- Complies with Vietnam's Decree 288/2025 on flights
Smart cameras
- Security AI: intrusion, strangers, smoke and fire
- Periodic shots as growth evidence
- Transparent livestream for buyers
- Automatic face blurring for workers
Technology
Open source, no vendor lock-in
- Web
- Next.js, TypeScript, MapLibre
- Mobile
- Flutter, offline local database
- Backend
- Node.js (NestJS), Python FastAPI for AI
- Messaging
- REST, GraphQL, gRPC, Kafka, MQTT
- Data
- PostgreSQL, PostGIS, pgvector, TimescaleDB, S3
- Infrastructure
