Security
Accounts done properly
Hashed passwords, short-lived tokens, refresh rotation with theft detection, and brute-force protection.
Under the hood
Built like infrastructure, not a demo
A multi-agent AI backend, a hardened API and a fast web app, designed to give farmers answers they can trust, quickly and affordably, at scale.

The stack
Three services, each doing one job well
| Web app | Next.js with React, Tailwind and a hand-built design system.Light and dark themes, three languages, installable on phones. |
|---|---|
| API | Node.js and Express with PostgreSQL.Accounts, farms, sensor data, plans, token budgets, streaming chat and voice. |
| AI backend | Python and FastAPI: an orchestrator coordinating six expert agents.Validated inputs and outputs, dependency-aware scheduling, conflict checks. |
| Language | GPT-4.1 models for understanding and answers.Answers written only from verified agent results. |
| Voice | GPT-4o transcription and speech.Sentence-by-sentence playback: the first words play while the rest is written. |
| Sensors | Blynk soil probes: air, moisture, temperature, EC, pH, N-P-K.Synced every 15 minutes; bad readings are dropped, not stored. |

Core Architecture
The Neural Core
Driving Every Decision
FarmXpert's multi-agent processor, sixteen specialized AI modules on a single intelligent substrate, routing real-time farm intelligence at sub-200ms latency.
Trust
Designed to be safe with a farmer's data
Privacy
Private by default
Farm data is visible only to its owner. Sensor tokens are never shown to anyone else.
Cost
Fair-use budgets
Every AI call is metered per farmer and day, so the service stays affordable for everyone.
Accuracy
No invented facts
The language model may only rephrase what the agents verified, numbers are copied, never guessed.
