Farm To Table: K-Tech NAIN State-Level Agricultural Platform

A state-level government initiative for Karnataka’s K-Tech NAIN program—Farm To Table revolutionizes agricultural commerce by creating a transparent, zero-commission marketplace that eliminates intermediaries and ensures farmers receive fair prices for their produce through direct buyer connections.

Project Overview

Government Initiative Context

Farm To Table was developed as part of Karnataka State Government’s K-Tech NAIN initiative, a program focused on leveraging technology to transform traditional agricultural supply chains. This project was specifically handed over to me by ATME College of Engineering based on demonstrated technical expertise in full-stack development and ability to deliver production-grade government systems.

Critical Problem Statement

Traditional agricultural supply chains in Karnataka suffer from:

• 30-40% intermediary commission fees drastically reducing farmer income
• Complete lack of transparency in pricing and product sourcing
• Complex multi-layered commission structures benefiting middlemen over producers
• Farmers receiving unfair compensation despite producing quality crops
• No direct market access for small and marginal farmers

Strategic Solution

Farm To Table addresses these systemic issues through:

• Zero-commission platform design allowing 100% farmer profit retention
• Direct farmer-to-buyer connections eliminating all intermediaries
• Transparent pricing mechanisms with complete visibility for all parties
• Integrated UPI payment system enabling instant direct transactions
• Role-based platform architecture maintaining neutrality in all dealings
• Government-backed credibility through K-Tech NAIN association

Technical Architecture

System Design Philosophy

The platform follows a minimal, essential-features-only approach:

• Simplicity: Only core features needed for discovery and trust building
• Transparency: Complete visibility of participants and transaction details
• Zero Lock-in: No platform dependency for payments or logistics coordination
• Free by Design: No hidden charges, commissions, or platform fees whatsoever

Full-Stack Technology Stack

Frontend Architecture

// Next.js 16.0 App Router with React 19.2
// Component-based architecture with role-specific routing

// Farmer Dashboard Component
export default function FarmerDashboard() {
  const [products, setProducts] = useState([]);
  const [deals, setDeals] = useState([]);
  
  // Real-time Firestore synchronization
  useEffect(() => {
    const unsubscribe = onSnapshot(
      collection(db, 'products'),
      (snapshot) => setProducts(snapshot.docs.map(doc => ({
        id: doc.id,
        ...doc.data()
      })))
    );
    return unsubscribe;
  }, []);
  
  return <ProductGrid products={products} />;
}
