Mobile case study

A multilingual marketplace connecting farmers and fertilizer plants

OrganiX is a mobile marketplace designed around a local agricultural supply chain in Navsari, Gujarat. Farmers can buy organic fertilizer from plants and sell eligible raw material back through the same application.

01 / The problem

What the team needed to fix

The local market involved two connected transactions: farmers needed access to organic fertilizer, while plants needed suitable raw material. Information and ordering were difficult to coordinate through informal channels.

The mobile experience also needed to be understandable for users with different language preferences and levels of technical comfort.

02 / The build

How I approached the system

Our team built a Flutter application with Firebase and Node.js services. The app supports product discovery, two-way marketplace flows, OTP verification, multilingual interfaces and order history.

The project was developed as an academic team project and won a state-level SSIP hackathon in 2023.

Common questions

Useful context before a similar build

Yes. Flutter can support multilingual product browsing, accounts, orders, notifications and marketplace workflows across mobile platforms.

Yes. Firebase authentication or another phone verification service can support an OTP-based account flow.

It reduces friction for farmers who are more comfortable reading instructions and completing transactions in a local language.

Yes. Role-aware navigation can give each account the actions it needs while keeping the shared marketplace and order data consistent.

The project uses a Node.js backend with Firebase services for authentication and application data.

OrganiX was a team project developed for the SSIP hackathon. The case study presents the implemented mobile workflow without describing it as a commercial deployment.
