Bartergram: Multi-Platform Influencer Marketing System

Spent 1 year as the sole technical lead building a complete influencer marketing platform consisting of mobile app, web dashboard, marketing website, and backend API. This was my most comprehensive full-stack project covering the entire product development lifecycle.

Technical Challenge

Building a complete ecosystem where brands could discover influencers, manage campaigns, and track deliverables across multiple platforms. Required handling complex user roles, real-time communication, payment processing, and social media integration.

Architecture Overview

Mobile App: React Native + Expo for cross-platform iOS/Android development

Web Dashboard: Next.js 14 with TypeScript for multi-role admin interfaces

Backend API: Node.js + Express with PostgreSQL and Prisma ORM

Authentication: OAuth with role-based permissions (Admin, Brand, Influencer)

Payments: Razorpay integration for subscription management

Cloud: AWS + Google Cloud for deployment and storage

Key Systems Built

Multi-Role Dashboard

Admin panel for platform management and user verification

Brand interface for campaign creation and influencer discovery

Influencer dashboard for deal tracking and content submission

Real-time approval workflows with notification systems

Mobile Application
