How I Built Viciniti — A Location-Based Marketplace

Viciniti started with a simple observation: buying and selling locally is still unnecessarily hard. Existing platforms are either too broad, lack trust mechanisms, or don't account for the hyper-local nature of community commerce.

The Idea

The core idea was simple — a marketplace where everyone within the same geographic area could buy and sell items, offer services, and hire locally. Trust-based, peer-to-peer, and community-first.

The Architecture

Viciniti is a full-stack application. The frontend is built with Next.js and Tailwind CSS, giving us a fast, responsive experience out of the box. The backend handles user authentication, listings, real-time messaging, and payment processing.

Payments with Flutterwave

One of the most important decisions was choosing Flutterwave for payments. It's well-suited for the Nigerian market, supports multiple payment methods, and has a reliable API. Revenue is generated through a 5% transaction fee on all completed payments — keeping the platform sustainable without charging users upfront.

The Single-Role Model

One of the most interesting design decisions was the single-role user model. Every account can simultaneously act as a buyer, seller, service provider, and client. This removes friction — you don't need multiple accounts, and you can switch between roles seamlessly within the same session.

Real-Time Messaging

Real-time messaging was built to facilitate communication between buyers and sellers before a transaction is completed. This builds trust and reduces the risk of failed transactions.

What's Next

Viciniti is live at viciniti-frontend.vercel.app. The next steps include expanding the verification system, improving location accuracy, and rolling out to more communities.
